I have firefox 3.26 or something like that on my ubuntu linux 10.04 machine. I only tried to install/update firefox 7.0 and it would not let me do this. I got a tar.biz2 file and when I opened it with archive manager, the compression software, it just had a bunch of binary files and wouldn't do anything at all so I extracted them, but that did not help. It still would not do anything. How do I upgrade my firefox browser and how do I get my firefox icon back on my desktop? Or shall I uninstall firefox and install another version or what? Is 7.0 not compatible with Ubuntu Linux? And if I am running the correct firefox browser for Linux, how do I update firefox in the ubuntu software update? I have tried this.
