It was also the newest version of stupid Firefox - the last two have been a nightmare also - almost on a par with MS updates. Both these companies now are now exceeding their capabilities and should leave programming to the experts

I could not agree more! I have had such an awful time with FIREFOX on the last updates! It's horrible. I am getting this message also no matter WHAT I DO! I feel your pain. So tired of it.

I just took a look at this link:

https://www.repairwin.com/firefox-xpcom-...

From repairwin.com which was the first link for a Google search: Firefox couldn't load xpcom

Then I just tried the first method of running the Firefox installer again and Firefox ran fine.
