It seems like we just began using 2.0, but 3.0 will be here before we know it. The final alpha has been released to developers, with a first beta available by the end of the month. That beta will be a feature-complete version of 3.0, which means only bugs will be the focus before the final release. At that time, developers will likely begin updating their extensions to function properly with it, as well. Since 2.0, I’ve had countless issues with the browser, so I am looking forward to seeing if 3.0 will improve upon it’s stability.
I just took the new version for a quick test drive and found that, as with previous alphas, it’s faster than Firefox 2 but it still has a ways to go before it’s stable and ready for the public. We’ll do a more detailed review of Firefox 3 when the first beta arrives. I’m particularly interested to see the revamped download manager and the rest of the Places improvements.
