A couple of days ago, my work laptop popped up a message that said: (from firefox) couldn't load XPCOM (OK)

Today, same work computer, another message popped up from firefox: Entry point not found. The procedure entry point ?WindowsOleAut32initialization@mozilla@@YA_NXZ could not be located in the dynamic link library C:\Users\Berlye\AppData\Local\Mozilla Firefox\xul.d

I have absolutely no idea what this means except that FireFox will not open. I am a very senior citizen and totally electronically challenged, so I need help in a-b-c fashion as to what this means and why I can't open Firefox on my work laptop.

Thank you.

Install Firefox again with a full installer. You shouldn't lose any data.

The full offline setup for Windows can be downloaded from https://www.mozilla.org/firefox/all/#product-desktop-release as downloading Firefox for Windows from mozilla.org may serve you the small online stub installer.

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 may have to disable security software temporarily in case the problem persists.
