Firefox won't start up
When I try to start Firefox, the following dialog box appears:
XUL Runner Error: Platform version 128.0.3 not compatible with minVersion >= 128.0 maxVersion <= 128.0
Clicking the OK button closes the attempt to start Firefox.
Do I need to reinstall the latest version? If I do, will all my info be saved? Jan

Hi janhsvec,
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. You shouldn't lose any data if you download the full installer from our official source.
Sorry about the inconvenience!
