Mozilla has addressed issues causing Firefox to crash on macOS and to freeze with a non-responding blank window when starting on Windows 11 systems.
According to the user who first reported the Windows freeze issue, the bug likely impacts Firefox users running Windows 11 who have also installed this month's KB5023706 cumulative update.
The crash report sent to Microsoft after the Firefox process crashes says the web browser "Stopped responding and was closed" because a "Problem caused this program to stop interacting with Windows."
The user who reported the issue added that after uninstalling the KB5023706 Windows update, Firefox again started as expected.
"Fixed a bug causing Firefox to freeze on startup for some Windows users," Mozilla says in the Firefox 111.0.1 release notes.
"Fixed a crash on macOS while pinch-zooming under some circumstances," Mozilla added in the Firefox 111.0.1 changelog.
