125.0.3 Firefox Release

April 29, 2024

Version 125.0.3, first offered to Release channel users on April 29, 2024

Fixed

  • Fixed an extra blank tab with an address of https://0.0.0.1 sometimes appearing when attempting to launch Firefox when it is already running (bug 1892612).

  • Fixed an issue that could cause incorrect font selection in some situations for users with the Japanese locale set (bug 1892363).

  • Fixed text corruption when dragging text containing unicode characters on Linux systems (bug 1888202).

  • Fixed a correctness error when checking arguments.length (and not using arguments otherwise) inside of a generator or async function (bug 1892699).

  • Fixed an issue that could lead to inconsistent focus handling of <select> elements when opened (bug 1893177).

Unresolved

  • Some users have reported seeing long hangs when clicking on the address bar due to the new Clipboard Suggestion feature. Disabling this functionality by unchecking the "Clipboard" box in about:preferences#search should resolve the hangs for impacted users. The underlying performance issue will be addressed in a future Firefox release.
