If you follow install procedures of Firefox 3.5 on Ubuntu, it will setup a new Mozilla browser instance named Shriketo “Shiretoko”, and in your main menu will appear as “Minefield”.

I had it installed, but removed it. I’ll wait for final release in default apt sourcelist. Also removed entries there I added using the tutorials. Why? Not much of a reason, I just prefer Firefox in the title bar. I’d like it even better if they change letter “e” in place of the globe there
