Upgraded to 25.0 release about 2 weeks ago (on Mountain Lion). Yesterday noticed the app slowing down considerably (beach ball) and memory use shot up, closed the app and re-opened. Upon reopening FF took a while and then presented a list of most of installed extensions/plugins as incompatible, when I then verified release number FF showed 10.0.0. Overlaying it with release 25.0.1 works for 5-10 minutes, then the app freezes and upon restart reverts back to 10.0.0. Tried deleting it, overlaying it, nothing works and I am not sure what to try next and not even sure how a much older release installs itself.

Try to do a FULL install from

Mozilla.org or

Firefox In Any Language.

Did you look for that older version of Firefox in the Finder?

Also make sure that you install the current Firefox release properly.
