125.0.2 Firefox Release

April 22, 2024

Version 125.0.2, first offered to Release channel users on April 22, 2024

Fixed

  • Reverted the changes recently shipped in Firefox 125 that more proactively blocked downloads from potentially untrustworthy URLs. The changes caused unexpected problems with downloading files in some situations. We plan to fix and re-enable these protections in a future release. (Bug 1892069)

Unresolved

  • When attempting to launch Firefox while it is already running, an extra blank tab with an address of https://0.0.0.1 may sometimes appear. The cause of this has been identified and will be resolved in an upcoming release.
