Mozilla Trademark Policy

Updated: October 30, 2009

List of Mozilla Trademarks

You can see a complete list of the Mozilla trademarks. As other trademarks are created or registered, this list will be updated. As used in this policy, "trademarks" means not just Mozilla's logos, but also the names of its various products and projects, as well as the names Mozilla and Mozilla.org, also called word marks, (collectively "Mozilla Marks").

Introduction

This document outlines the policy of the Mozilla Foundation ("Mozilla," for short) regarding the use of the Mozilla Marks. Any use of any Mozilla trademark must be in accordance with this policy. Any use that does not comply with our trademark policy or does not have written authorization from us is not authorized. Any goodwill generated by the use of any Mozilla Marks inures to the benefit of Mozilla.

Mozilla's Trademark Policy attempts to balance two competing interests: Mozilla's need to ensure that the Mozilla Marks remain reliable indicators of quality, source, and security; and Mozilla's desire to permit community members, software distributors, and others with whom Mozilla works to discuss Mozilla's products and to accurately describe their affiliation with us. Striking a proper balance is a tricky situation that many organizations—in particular those whose products are distributed electronically—wrestle with every day and we've attempted to balance it here.

Underlying our trademark policy is the general law of trademarks. Trademarks exist to help consumers identify, and organizations publicize, the source of products. Some organizations make better products than others; over time, consumers begin to associate those organizations (and their trademarks) with quality. When such organizations permit others to place their trademarks on goods of lesser quality, they find that consumer trust evaporates quickly. That's the precise situation that Mozilla seeks to avoid. People's trust in our name and products is crucial to us—especially, when it comes to intangible products like software, trust is all consumers have to decide on which product to choose. We also are the caretakers of the trust our community members have placed in us. We created this Trademark Policy to protect both the public's and our community's trust in the Mozilla Marks.

In addition, on an all too frequent basis, we receive reports about websites selling the Mozilla Firefox browser, using the Mozilla Marks to promote other products and services, or using modified versions of the Mozilla Marks. The problem with these activities is that they may be deceptive, harm users, cause consumer confusion, and jeopardize the identity and meaning of the Mozilla Marks. Such cases range from good intentions but improper use of the trademarks (e.g., overenthusiastic fans), to people intentionally trading on the brand for their own benefit and/or to distribute modified versions of the product, to a clear intent to deceive, manipulate and steal from users in a highly organized and syndicated fashion. When we receive reports of such activities, or identify problematic activities, we analyze the reports and treat each case individually based on the intent and severity of the matter.

In creating our trademark policy, we seek to clarify the uses of the Mozilla Marks we consider legitimate and the uses we do not. Although Mozilla's Trademark Policy is composed of a number of specific rules, some contained in companion documents, most reflect the overarching requirement that your use of the Mozilla Marks be non-confusing and non-disparaging. By non-confusing, we mean that people should always know whom they are dealing with, and where the software they are downloading comes from. Websites and software that are not created or produced by Mozilla should not imply, either directly or by omission, that they are. By non-disparaging, we mean that, outside the bounds of fair use, you can't use the Mozilla Marks as vehicles for defaming us or sullying our reputation. These basic requirements can serve as a guide as you work your way through the policy.

Our Trademark Policy begins by outlining some overall guidelines for the use of the Mozilla Marks in printed materials. It then addresses a series of more specific topics, including the use of Mozilla's trademarks on distributions of Mozilla's binaries, linking to Mozilla's website(s), and the use of Mozilla Marks in domain names. At various points, this policy links to other documents containing additional details about our policies.

We also have a trademark policy FAQ as a companion document to this policy.

Overall Guidelines for Printed Materials and Web Sites

We encourage the use of the Mozilla Marks in marketing, and other publicity materials related to Mozilla or the relevant Mozilla product. This includes advertising stating that a person or organization is shipping Mozilla products. Of course, any use of a Mozilla trademark is subject to the overarching requirement that its use be non-confusing. Thus, you can't say you're raising money for Mozilla when you're actually raising it for a localization project, say that you're reviewing or distributing the Mozilla Firefox Internet browser when you're actually reviewing or distributing a modified version of Firefox, or use the Mozilla logos on the cover of your book or on your product packaging.

Although many uses of the Mozilla Marks are governed by more specific rules, which appear below, the following basic guidelines apply to almost any use of the Mozilla Marks in printed materials, including marketing, articles and other publicity-related materials, and websites:

  • Proper Form - Mozilla's trademarks should be used in their exact form -- neither abbreviated nor combined with any other word or words (e.g., "Thunderbird" rather than "T-Bird" or "Thunderbinary");
  • Accompanying Symbol - The first or most prominent mention of a Mozilla trademark should be accompanied by a symbol indicating whether the mark is a registered trademark ("®") or an unregistered trademark ("™"). See our Trademark List for the correct symbol to use;
  • Notice - The following notice should appear somewhere nearby (at least on the same page or on the credits page) the first use of a Mozilla trademark: "[TRADEMARK] is a ["registered", if applicable] trademark of the Mozilla Foundation";
  • Distinguishable - In at least the first reference, the trademark should be set apart from surrounding text, either by capitalizing it or by italicizing, bolding or underlining it. In addition, your website may not copy the look and feel of the Mozilla website, again, we do not want the visitor to your website to be confused about which company he/she is dealing with.
  • Comply with Visual Guidelines - any use of the Mozilla Marks must comply with our Trademark and Logo Usage Policy and our Visual Identity Guidelines at:

Software Distributions

Unaltered Binaries

You may distribute unchanged official binaries (i.e., the installer file available for download for each platform (code + config) and not the program executable) downloaded from www.mozilla.com or www.mozilla.org to anyone in any way, subject to governing law, without receiving any further permission from Mozilla. If you want to distribute the unchanged official binaries using the Mozilla Marks, you may do so, without receiving any further permission from Mozilla, as long as you comply with this Trademark Policy and you distribute them without charge. However, you must not remove or change any part of the official binary, including the Mozilla Marks. On your website or in other materials, you may truthfully state that the software you are providing is an unmodified version of a Mozilla application, keeping in mind the overall guidelines for the use of Mozilla Marks in printed materials, detailed above. We suggest that, if you choose to provide visitors to your website the opportunity to download Mozilla product, you do so by means of a link to our site, to help ensure faster, more reliable downloads. (See the section on Linking, below.)

If you choose to distribute Mozilla binaries yourself, you should make the latest stable version available (of course, you probably want to do so as well). If you compile Mozilla unmodified source code (including code and config files in the installer) and do not charge for it, you do not need additional permission from Mozilla to use the relevant Mozilla Mark(s) for your compiled version. So that users get the latest code and security releases, we encourage you to always distribute the most current official release. The notification requirements of the Mozilla Public License have been met for our binaries, so although it's a good idea to do so, you are not required to ship the source code along with the binaries.

In addition, if you are distributing Mozilla binaries yourself, and wish to use the Mozilla Mark(s), you may not (a) disable, modify or otherwise interfere with any installation mechanism contained in a Mozilla product; (b) use any such installation mechanism to install any plug-ins, themes, extensions, software, or items other than the Mozilla product; or (c) use or provide any program, mechanism or process (other than an installation mechanism contained in the Mozilla product) to install such product. Any use of a meta-installer would require our prior written permission.

If you are using the Mozilla Mark(s) for the unaltered binaries you are distributing, you may not charge for that product. By not charging, we mean the Mozilla product must be without cost and its distribution (whether by download or other media) may not be subject to a fee, or tied to subscribing to or purchasing a service, or the collection of personal information. If you want to sell the product, you may do so, but you must call that product by another name—one unrelated to Mozilla or any of the Mozilla Marks (see the sections on "Modifications" and "Related Software" below). Remember that we do not want the public to be confused.

Official Localized Releases

Where Mozilla doesn't distribute localized versions (e.g., Mozilla Firefox) localization teams that have been recognized by Mozilla may identify and distribute Official Localized Releases of the Mozilla products using Mozilla's trademarks. Because Localization Teams and Official Localized Releases represent the Mozilla project, they are expected to abide by strict guidelines. For more information, please see Mozilla's Trademark Policy for Localization Projects.

Modifications

If you're taking full advantage of the open-source nature of Mozilla's products and making significant functional changes, you may not redistribute the fruits of your labor under any Mozilla trademark, without Mozilla's prior written consent. For example, if the product you've modified is Firefox, you may not use Mozilla or Firefox, in whole or in part, in its name. Also, it would be inappropriate for you to say "based on Mozilla Firefox". Instead, in the interest of complete accuracy, you could describe your executables as "based on Mozilla technology", or "incorporating Mozilla source code." In addition, you may want to read the discussion on the "Powered by Mozilla" logo.

In addition, if you compile a modified version, as discussed above, with branding enabled (the default in our source code is branding disabled), you will require Mozilla's prior written permission. If it's not the unmodified installer package from www.mozilla.com, and you want to use our trademark(s), our review and approval of your modifications is required. You also must change the name of the executable so as to reduce the chance that a user of the modified software will be misled into believing it to be a native Mozilla product.

Again, any modification to the Mozilla product, including adding to, modifying in any way, or deleting content from the files included with an installer, file location changes, added code, modification of any source files including additions and deletions, etc., will require our permission if you want to use the Mozilla Marks. If you have any doubt, just ask us at trademarks@mozilla.com.

Extensions, Themes and Plugins

At the same time as we seek community involvement in the development of the Mozilla products, we want to protect the reputation of these products as high-quality and lightweight, with simple, usable interfaces. If you want to ship extensions, themes or plug-ins installed by default or as part of the same installation process as the Mozilla products (as opposed to, say, linked as XPIs from the default start page), and you plan on distributing them under any Mozilla Marks, you must first seek approval from us. What we find acceptable will depend on the effect of the extensions, themes and plug-ins on the Mozilla product. To give examples, changing the theme of one product to another, equally high-quality and aesthetically pleasing theme would be considered. A combination of ten different extensions with three toolbars and seven context menu items probably wouldn't be. See our Partners page to find out more about contacting us to discuss your proposed changes.

Related Software

Mozilla products are designed to be extended, and we recognize that community members writing extensions need some way to identify the Mozilla product to which their extensions pertain. Our main concern about extensions is that consumers not be confused as to whether they are official (meaning approved by Mozilla) or not. To address that concern, we request that extension names not include, in whole or in part, the words "Mozilla", "Firefox", or "Thunderbird" in a way that suggests a connection between Mozilla and the extension (e.g., "Frobnicator for Firefox," would be acceptable, but "Firefox Frobnicator" would not).

Linking

We invite you to link to Mozilla's website(s) for the purpose of allowing your visitors to download Firefox and Thunderbird, by using the banners and buttons we provide, subject to the restrictions below.

This use is allowed as long as you:

  • Follow the Mozilla Trademark Policy.
  • Point the destination URL to the official Mozilla product website. You may not use a Mozilla banner or button to point to your own web site and/or to download a modified version of Firefox or Thunderbird.
  • Don't alter any of the Mozilla Marks including our logos.
  • Don't do anything that might confuse visitors to your website into mistaking the origin of software being downloaded—whether the software is Mozilla's or yours.

You may customize the buttons in the following ways:

  • Modify the background color of the button or banner.
  • Localize the text (but not the Mozilla Marks).
  • Change the size of the button or banner.

Remember the Mozilla Marks must not be altered in any way. If your use of these banners or buttons violates our Trademark Policy, your use is unauthorized.

Best Viewed With Buttons. Also, please remember that we disapprove of and do not provide "Best Viewed With" buttons, when used in connection with the Firefox Internet browser. We believe the web is best viewed with any standards-compliant browser and do not want to promote browser specific sites. However, if you must use a statement, please use something like "Try our site using the Firefox web browser" or "We recommend using Firefox web browser or other standards-compliant browsers."

Site Icons (favicons). If you plan to use a Mozilla trademark as a site icon, you need to request permission.

Domain Names

If you want to include all or part of a Mozilla trademark in a domain name, you have to receive written permission from Mozilla. People naturally associate domain names with organizations whose names sound similar. Almost any use of a Mozilla trademark in a domain name is likely to confuse consumers, thus running afoul of the overarching requirement that any use of a Mozilla trademark be non-confusing. If you would like to build a Mozilla, Firefox Internet browser, or Thunderbird e-mail client promotional site for your region, we encourage you to join an existing official localization project.

To receive written permission, please download and follow the directions as outlined in the Domain Name License.

Services Related to Mozilla Software

If you offer services related to Mozilla software, you may use Mozilla's word marks in describing and advertising your services relating to a Mozilla product, so long as you don't violate these overall guidelines for the use of Mozilla's trademarks or do anything that might mislead customers into thinking that either your website, service, or product is a Mozilla website, service, or product, or that Mozilla has any direct relationship with your organization. For example, it's OK if your website says, "Internet browser customization services for Firefox available here." It's not OK, though, if it says, "Firefox Internet browser customization services sold here," or "custom Firefox Internet browsers available here," since the first suggests that Mozilla is related to your business, and the second is confusing as to whom -- you or Mozilla -- performed the customization. In addition, your website may not copy the look and feel of any Mozilla website. Again, we do not want the visitor to your website to be confused with whom she/he is dealing. When in doubt, err on the side of providing more, rather than less, explanation and information.

If you are offering services for Mozilla software (for example, support), you may not tie the download of the Mozilla product with the purchase of your service. The download of the Mozilla product using the Mozilla trademark may not be connected in any way to the purchase of your service. The purchase, download, or acquisition of your services must be a completely separate transaction from the download of the Mozilla product. You must provide a prominent statement that (i) the Mozilla product is available for free and link directly to our site; (ii) the purchase, download, or acquisition of your service is separate from the download of the Mozilla product; and (iii) your service is not affiliated with Mozilla.

Mozilla Marks and Merchandise

When it comes to the Mozilla Marks, there are some cool things you can do and some cool things you can't do - at least not without asking Mozilla.

You may make t-shirts, desktop wallpaper, or baseball caps with Mozilla Marks on them, though only for yourself and your friends (meaning people from whom you don't receive anything of value in return). You can't put the Mozilla Mark(s) on anything that you produce commercially (whether or not you make a profit) -- at least not without receiving Mozilla's written permission. Mozilla contracts with third party vendors that provide Mozilla products for sale. These vendors own and operate the Mozilla Store and the Mozilla Community Store. The Mozilla Store offers T-shirts, CDs and other merchandise branded with Mozilla product logos. The Mozilla Community Store offers items that are designed by a member of the worldwide Mozilla community.

There is one additional broad category of things you can't do with Mozilla's Marks.

  • Produce modified versions of them. A modified mark also would raise the possibility of consumer confusion, thus violating Mozilla's trademark rights (remember the overarching requirement that any use of a Mozilla Mark be non-confusing?).

High Resolution Copies. We are in the process of working out the best way to allow access to the vector files for the Mozilla Marks, which may require additional terms. In the meantime, if you need to use a high-resolution copy of Mozilla Marks please contact the Mozilla Corporation for Firefox and Thunderbird trademarks, or the Mozilla Foundation for other trademarks and we will try to accommodate your request.

Things You Can Do—Summary

To summarize, provided that the use adheres to our trademark policy and visual guidelines, here are some of the things that you can do with the Mozilla Marks that do not require our permission:

  • use the Mozilla Marks in marketing, and other publicity materials related to Mozilla or the relevant Mozilla product;
  • distribute unchanged Mozilla product(s) (code + config) for each platform downloaded from www.mozilla.com or www.mozilla.org as long as you distribute them without charge;
  • describe your executables as "based on Mozilla technology", or "incorporating Mozilla source code;"
  • link to Mozilla's website(s) by using the banners and buttons we provide to allow your visitors to download Firefox and Thunderbird;
  • use Mozilla's word marks in describing and advertising your services or products relating to a Mozilla product, so long as you don't do anything that might mislead customers. For example, it's OK if your website says, "Internet browser customization services for Firefox available here;" and
  • make t-shirts, desktop wallpaper, or baseball caps though only for yourself and your friends (meaning people from whom you don't receive anything of value in return).

Questions

We have tried to make our trademark policy as comprehensive as possible. If you're considering a use of a Mozilla trademark that's not covered by the policy, and you're unsure whether that use would run afoul of Mozilla's guidelines, feel free to contact us at trademarks@mozilla.com and ask. Please keep in mind that Mozilla receives lots and lots of similar questions, so please review all available documentation, including the Frequently Asked Questions (FAQ) before contacting us.
