The really easy way to use Firefox 3.5.x in Slackware 12.2 is to simply download the FF 3.5.x.tar.bz installer from mozilla.com to your home directory. Then untar it. Then cd into the ~/firefox/plugins directory, and make symlinks so your plugins work:
Code:
cd ~/firefox/plugins
ln -s /usr/lib/mozilla/plugins/* .
NOTE: There is a space, then a period ".", at the end of that command.
Then just create a shortcut for FF 3.5 on your desktop. In XFCE, simply use thunar to navigate to the ~/firefox directory and right-click on the Firefox icon and choose "send to > Desktop (create link)". Then just click on that link on your desktop to launch FF 3.5.
Or you can launch FF 3.5 from the terminal like this:
Code:
cd ~/firefox
./firefox &
I use FF 3.5 in Slackware 12.2 this way and it works fine. Of course, this does not make it available system wide. It will work for your user though. Other users could do the same thing if you are running a multi-user system.
