Firefox One and a Half
Downloaded firefox 1.5, like the last time I tried to install firefox things refused to go smoothly. Interesting that the download site has changed to mozilla.com. What hasn't changed is the insistence that they do a browser detection and try to force a file down your throat.
The firefox-1.5.tar.gz file that was delivered does not contain an installer, you just expand it and run. But run it will not.
