Description

Sites can use the _search target to open links in the Firefox sidebar. Two missing security checks allow malicious scripts to first open a privileged page (such as about:config) and then inject script using a javascript: url. This could be used to install malicious code or steal data without user interaction.

Workaround

Disable Javascript
