WTF, indeed.
Idly reading this thread and pressed Help. About Firefox. I'm current on 6 but it said - after running a check - you are currently on the release update channel. (their bold.)
Wassssattt all about? Can I not look in there anymore without getting updated? My last two updates were uninvited.
Oh, I did take on board, and value, the comment above about the need to update. Thanks for that.
