My current install of Firefox seems to be corrupted, because every time i try starting firefox, even in safe mode, it says "Could not load XPCOM". So my only option now is to reinstall, but i have some password and my search history and bookmarks and generall data to backup. So my question is how can i do this. Im on a Windows 10 22H2 Machine, and i am a pretty expirienced computer user.

An error message about XPCOM missing or about platform version usually happens because of a failed Firefox update that left you with a mixture of old and updated files in the Firefox program 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 need to 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.
