I am using a friends Computer, since I cannot enter my laptop Firefox is not working: Should I re install? Or can I get I Phonecall?????

The screen shows only XUL Error: platform version 124.1 is not compatible min=124.0 max=124.0

An error message like XPCOM missing or about platform version or entry points not found can happen because of a failed Firefox update that left you with a mixture of old and updated files in the Firefox installation folder. This can happen in case security software was keeping a handle of some of the files in the Firefox program folder preventing Firefox from replacing all the files. You can do a clean reinstall and remove the Firefox program folder to ensure that all files are replaced. You may have to disable security software temporarily in case the problem persists.
