are you using 32bit or 64bit Ubuntu? And are your firefox downloaded form their site or installed from standard repo? – Anwar Shah Sep 25 '12 at 8:02
32 bit ubuntu, at first my firefox is working ,recently i upgraded my gcc version, there after its not working. – alex Sep 25 '12 at 9:01

Reset Firefox ! ;)

Open terminal (Ctrl +Alt+T)

Enter the command below to reset & clean all data in your Firefox

mv .mozilla/firefox .mozilla/firefox.bak

Then restart Firefox.

If it doesn't work. Try this command:

sudo apt-get clean; sudo apt-get update; sudo apt-get remove firefox; sudo apt-get install firefox

I wouldn't do that, the profile has little to do with library dependencies. – January Sep 25 '12 at 5:41

I would add sudo apt-get update first. Just to make sure he has latest repository information. – Dan Sep 25 '12 at 8:07
Thanks for replys, apt-get is not working, it seems. if try with sudo apt-get update , error--->>apt-get:/opt/quartus/linux/libstdc++so.6:version 'GLIBCXX_3.4.15 not found required by apt-get.This is the problem, any solutions? – alex Sep 25 '12 at 9:00
Uh-uh. That looks bad. Please start a new question with the exact error messages of apt-get. Also, post /var/log/dpkg.log. Something is rotten in your system, and probably you will have to install the libs manually. – January Sep 25 '12 at 9:20
