I finally got around to downloading and installing Firefox 3 today and on first inspection it does some to have a better look and feel and some nice improvement over version 2.
One thing I wasn't impressed with though was the installation process. Firefox uses a typical installation wizard but I was a little miffed to get to the final step before installation began to find a message indicating that Firefox was going to be made the default browser. Nowhere in the wizard did it give me the option of selecting whether or not I actually wanted Firefox to be the default browser, it just kind of made that decision for me and there was no option I could (de)select to tell it otherwise.
Now I know this isn't a life-and-death issue, particularly as I can always reset my choice of default browser after installation but it is an irksome irritation. I do quite a bit of work on web-based projects and I tend to install lots of browsers on my main development machine so that I can check that the web user interfaces I build work properly in all the major browsers. It gets to be a real pain in the butt if all the browsers continually engage in macho jockeying to be the top browser each time I upgrade one of them. So if any of the browser devs out there read this, please please please put an option in your installation routine that allows me to decide whether I want your browser to be my default.
