Have used Firefox many years w/o incident. Now I'm dealing with "Can't load XPCOM error". I have done everything as far as troubleshooting or stopping this with no results. ? is if I just ignore it will that be ok or cause problems in the future. My newly re-installed version is working fine, but I still get the error message. (I already lost all my book marks) THx!

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.
