I discovered in the course of trying to get rid of "Buzzdocks ads" adware nuisance that I'm on the firefox release candidate channel. Evidently Firefox is updating automatically and behind the scenes with release candidates. I'm right now on version 17.x. I figured this might not be such a great idea, but searching in the Firefox menus I don't see any way to change the way Firefox updates or doesn't update. WTH. Do I have to uninstall FF and reinstall to get some control?
