I receive this message every time I open Firefox the first time online, and with each new window or tab I open after that. I don't receive the message more than once if I only work in the original window. Other than the usual updates that always go on, I haven't added or deleted anything from my system.

This happened

Every time Firefox opened

== Not sure exactly when.

Do you get the error if you start FF in Safe Mode? https://support.mozilla.com/en-US/kb/Safe+Mode

I've tried starting Firefox multiple times both regular and safe modes. I do not get the error when starting in safe mode.

Since it doesn't happen in safe mode it is likely being caused by an extension. Please disable 1 by 1 until you find the cause http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+theme...

I found the extension causing the problem. It is MyPoints Point Finder 1.300.306. I tried updating it, but there are none available. It is currently disabled. Would removing it be a better strategy, or leave it disabled until an update is available?

Keeping it disabled is fine
