Mozilla released the 5'th beta of the Firefox 3 browser a few hours ago.

The new beta brings enhancements in the bookmark organizer, operating system integration and most important to me the speed in the javascript engine that so many sites depends on these days.

There are just 750 improvements since the last beta version, 250 fewer then the number of improvements between beta 3 and beta 4.

I think this will probably be  the last beta version before a release candidate even thou the "known issues" list is a bit larger then the one of the previous beta.

Here are the release notes and here is the download page for those of you that want to give it a try.
