Well this is a new record, two Firefox releases on the same branch in the same week. Today Mozilla pushed out Fx 126.96.36.199 to fix (for some) a major regression in the Fx 188.8.131.52 release from earlier this week. As is normal practice, most users will get an update notfication within the next 24-48 hours. Alternatively, users can get the new version by going to the Help Menu and selecting Check For Updates… or via getfirefox.com. For more information see the Fx 184.108.40.206 release notes.
