LizzieW - I remember seeing that at the time, but thankfully it doesn't seem to apply in my case. I much prefer to do updates at a time of my choosing.
I quite often get the pop-up telling me a new version is out & ignore it for a few days in case I come across too much negative feedback - keep getting the pop-ups but no auto-install.
Using XP in Firefox under Tools > Options > Advanced
Second option selected - "Check for updates, but let me choose whether to install them"
