Another gripe I have with Firefox (which I only use on the Lubuntu laptops I have) is that when it wants to update it insists that you restart it and won't let you open another page until you do.
Huh? This never happens to me and I usually don't restart when it nags me to for weeks, because it has a tendency to forget the previous session on updates.
It definitely does it. I'll be looking in to some issue (because that's 90% of using Linux on a device) and suddenly I won't be able to open any new tabs until I restart the browser.
