Firefox Release Notes

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).

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.
