I am using Ubuntu 9.04 (I know it is old, but I love it!), and want to update my firefox. It is currently running Firefox 3.6.11 and many web pages complain that "your browser is old". So I downloaded
firefox-20.0.tar.bz2 and as per these instructions installed it. Here is what they instruct to do:
I did exactly what it said to do. Actually there my current Firefox was not installed in the /opt directory, so I just placed the new one there and then did as it says in these instructions. But after so doing, the Firefox installer in my applications -> internet, would not open any Firefox. So I had to revert to the old one by doingIf you already had a previous Firefox version installed in the /opt directory, remove it with the following command:
sudo rm -r /opt/firefox
Now move the firefox directory (which was created in your Downloads folder during extraction) to /opt:
sudo mv firefox /opt/firefox20
If you want to use Firefox 20 as your default browser:
“Backup” the old Firefox launcher:
sudo mv /usr/bin/firefox /usr/bin/firefox-old
Create a symbolic link pointing to the new Firefox version:
sudo ln -s /opt/firefox20/firefox /usr/bin/firefox
No need to update your icons/shortcuts, they should now launch the new version of Firefox.
Your old Firefox version is still installed. If you want to use it, run firefox-old in a terminal or create shortcuts/icons referring to firefox-old.
Now the old one is again working fine. But how do I make the new one i.e. Firefox-20 active as my current browser?Code:sudo mv /usr/bin/firefox-old /usr/bin/firefox
