Had to start in safe mode disabling addons because in addition to everything else the new release of FF rebroke gmail. Here's the info you asked for:

I'm getting this message from within Firefox Help. Pretty sad when FF can't diagnose correctly the release I'm on.

this line is likely causing the problem as identifies your browser as firefox 6:

general.useragent.override: Mozilla/5.0 (Windows NT 6.1; rv:6.0) Gecko/20100101 Firefox/6.0

again please refer to this article in order to reset the user-agent settings in firefox: How to reset the default user agent on Firefox

It appears your useragent is set to Firefox 6 which would cause the help website to show you this out of date warning. Please try the solution in the article that Phillipp recommended - How to reset the default user agent on Firefox.

Made the change. Went out of FF but when I came back in it was back to the previous value.

When I come back in I have to go into Safe Mode since the recent release rebroke gmail. Don't know if safe mode causes the value to revert.

the firegloves extension that you have installed seems to fiddle with this setting: https://github.com/kboda/firegloves/blob/7ee00cdba156e199a858771bea7a98dfa5657674/firegloves-1.2.3-fx/defaults/preferences/defaults.js#L11

Yep. Disabled FireGloves and all is well. I'm going to remove it. Thanks for your help
