14.04 freezes after upgrade

[Linda]

Hi,
Silly question but what happens if you run firefox from a terminal, do
you get any errors in the terminal? (+ quitting the terminal SHOULD kill
f-f if it freezes)

Also did you install Ubuntu Gnome or did you put Gnome on top of another
Ubuntu? if so the firefox-Ubuntu-compatability layer or whetevr it's
called these days (the thingy that makes it work with Unity) MIGHT be
causing a conflict in Gnome?

Also a silly point to raise here (I'm sure I'll be shot down in flames
if I am incorrect) but does Gnome Fallback still exist, I am almost
certain that I've seen a discussion about the removal of the fallback
option. (personally I don't like the new Gnome but thats just me)

If the only issue is f-fox I am certain the need to re-install will NOT
be necessary, however back up your passwords (if you save them) and your
bookmarks (really easy to do from in f-f but MUST be a file somewhere!)

Happy hunting

Thanks for the suggestion to run Firefox from terminal. I don't have access to the machine tonight, but I will try that.
I upgraded from 12.04 LTS to 14.04 LTS and it had gnome flashback with Compriz and gnome flashback with Meta City as options.
Since a few of the machines I run are quite old they do not like unity and compriz but ran fine with gnome classic in 12.04 so
I just made them all that way. Plus honestly I prefer gnome classic and most of my users do not like change. This was my trial run
for doing upgrades instead of clean installs it saves a lot of time. I've always just done clean installs before to move to a new LTS version.
