I have upgraded my Ubuntu desktop using the following command,
sudo apt-get upgrade
After that my Firefox version gets changed into 10.0. For some reason we have run our softwares in Firefox version 3.6. So i have removed the Firefox by using the following command.
sudo apt-get remove --purge firefox
and reinstalled Firefox but again 10.0 got installed. So i have removed it again. And i have downloaded tar.gz file and extracted it. The same is working fine, however my old Firefox shortcuts icons were simply showing without default Firefox icon. How to bring it back?
