I have recently noticed that some plugins in my Firefox keeps updating by itself and it’s annoying because I didn’t allow this to happen as a user.
To easily fix these updates from automatically updating you (or bugging you), go to Tools->Options->Update then unclick all the boxes so your Firefox browser never wastes any bandwidth to check for updates.
I think updates are great but I don’t want my Firefox to keep checking for them every time I start my browser, it also takes a lot more time to load your browser when you are checking for updates. And yes, even 1 or 2 extra seconds is annoying as hell for bloggers like me who need that extra 1 or 2 seconds in life. 🙂
