Which os and which version of FF?

Sorry about that, I thought I had put that info in *embarassed* before I went to work (just got back). The original screen capture of the error is included now - I hope - it didn't load this morning for some reason.

I am on Win 7 (Home) and I am using the latest version (38.0.5) of Firefox which updated only several days ago.

It happened a few days ago and I reinstalled it. It worked for a few days but then this morning it crashed again which prompted me to ask the question.

Just got back and it seems to be working again - how long for, I don't know. I am more confused than ever! (I am not exactly a computer wiz...)

Try to set all plugins to "Ask to Activate" on the "Firefox/Tools > Add-ons > Plugins" page.

Make sure that all plugins are updated to the latest version.

Thanks Cor-el, I have checked that and as many of the plugins are marked "Ask to Activate" as will allow.

A couple of them only allow "Always Activate" or "Never Activate" (OpenH264 Video Codec provided by Cisco Systems, Inc. 1.4 & Primetime Content Decryption Module provided by Adobe Systems, Incorporated).

At the moment everything SEEMS to be working OK but this also happened a few days ago (and I reinstalled Firefox which seemed to fix the problem for a few days)

Thanks Fred, I will try some of the things in the articles to see if it avoids the problem.
