Ubuntu 8.04 Hardy Heron has been giving me a good time lately except for the web browsing experience. Firefox 3 beta 5 is included in Ubuntu 8.04 final as the default web browser even though its not stable. Above all, its not even compatible with Wordpress 2.5 and will keep bugging you now and then with new problems.
So whats the solution? Either get Opera for Linux or get back the old and mighty Firefox 2. Many users think that as Firefox 3 beta 5 has been included in the final release of Ubuntu 8.04 Hardy so probably there is no easy way to get rid of it and install Firefox 2 instead but in reality its very easy to do so.

Go to System → Administration → Software Sources and make sure you have enabled all software package repositories. Now open the Synaptic Package Manager and look for the following packages.
- firefox
- firefox-3.0
- firefox-3.0-dev
- firefox-3.0-gnome-support
Right click on all of these packages and “Mark for Removal”. Now find the following packages and right click to “Mark for Installation”
- firefox-2
- firefox-2-gnome-support
Click Apply once and then again click Apply. This will remove Firefox 3 beta 5 and will download and install Firefox 2. The web browser can then be accessed from Applications → Internet → Firefox 2 Web Browser







When you remove Firefox 3 select the complete removal option instead of just the remove option.
Thanks for sharing. I had installed firefox 2 on my Hardy Heron, which is through wubi installer on my Vista. But, I am not able to install any of the add-on on firefox 2. It says “firefox can’t install the file”. Simply not a single add-on I could install. I tried to find solution on google. But unfortunately nothing worked. If some1 can help.
Thanks.
