Firefox updates corrupts my PC

The update two days ago has left me with an error message: Platform version '131.0' is not compatible with MinVersions and MaxVersions 130.0.1

What can I do? This is the 3rd update corruption within the last 6 weeks - last time I was told to remove Firefox and install from new so lost at least 6 years history.

Hi Alan,

This is a known issue caused by a corrupted installation after a failed update. The workaround is to uninstall and then re-install Firefox to fix this issue while our team is working on a more permanent fix. I'm so sorry about your last experience with reinstalling Firefox, but you shouldn't lose any data if you download the full installer from our official source.
