500 Internal Server Error: An unknown error has occurred
When I open my browser, it immediately displays this error message. No matter what web site I navigate to, I get this message.
I have no problems with Internet Explorer, so I know this is limited to Firefox.
I've been gone for the past 5-6 days and just got home. It worked fine 5-6 days ago. The only change I noticed was that it installed an update to AdBlock Plus. Not sure why that would matter, but I uninstalled AdBlock Plus just to be sure. It didn't help- error is still occurring.
I also tried uninstalling and re-installing Firefox, but that didn't help either.
Anyone know why this is happening and what I can do to fix it?
Thanks!

It seems the same error was posted several times in this forum.

I resolved the issue by removing the "Relevent Knowledge" add-on. Now Firefox works normally.
