Mozilla team has released an update for Firefox and Mozilla Seamonkey to public. It's dubbed Firefox 220.127.116.11 and SeaMonkey 1.1.18. Both are stable version, meaning that they targeted for stabilizing the product and fixing critical problem, including security vulnerabilities, not adding new features to the products.
Meanwhile, Firefox 3.0 Beta 3 has been prepared before they release the first RC to public. I have been testing Beta 2 on Linux and it does works on general usage, but they could do better than that, since according to their announcements, there are still 61 P1 blocker for 3.0, meaning they need to work harder to squash all those bugs to 0.
