Re: Pot, kettle, black
I too was getting irritated by these update messages since they removed the "Never check for updates" option.
Some mitigations that helped are setting the following about:config options as follows.
app.update.doorhanger to false - stops the small/frequent notification message, however that leads to the larger (old style) on-screen notification popup (less frequently but still often enough).
So I set the following preference values to 2147483647 (The largest value possible) - and I haven't seen a notification since :-D
app.update.interval
app.update.idletime
I also had the following set to that value too - as was just playing about really.
app.update.badgeWaitTime
app.update.promptWaitTime
Biting the hand that feeds IT
