Hi there, Im on a windows 10(ish) and yesterday got this problem after the auto update to firefox 133.0.3 - Update is not working. error window says platform version 133.0.3 is not compatible with minVersion >= 133.0... how can I fix this?

I've seen that there was a similar issue back in October with a previous version. Tried to follow instructions and reinstaled firefox from mozilla. But the problem is still there. Restarted after reinstalling and still getting the same error message. ((( Please help )))

Sorry, this usually indicates that the updater didn't successfully replace all of the previous version files with new ones. You can try re-running the full installer to refresh the program files. Those are here:

If the problem continues, you may need to shut down/restart Windows to free up file locks in order to complete the update.
