So should you or should you not be using Firefox 3 yet? I would say for 90% of the population or people using Firefox, no. You should at least wait for the release candidate versions or the final version. The fact of the mater is, even though Firefox 3 looks good it still is not done yet. The idea of bringing this topic up started after reading a post over at Cybernet News:
There is a lot of talking going around the Internet about Firefox 3 Beta being ready for mass usage. It’s because of an article by Reuters where the creators of Firefox supposedly told them that the Firefox 3 Beta is ready for everyone to use after months of being in development.
So I thought I would do what I can to help spread the words too about Firefox 3 being nice, pretty but not ready for prime time just yet. Just to give you an idea of how long you should wait – I haven’t even replaced Firefox 2 yet. Personally I’ll wait till it goes into the "release candidate" versions so that I can get ahead of the curve with some of your questions about it.
Also major "shame shame" on Reuters for not doing their homework on this.
