Sweet.  I didn’t see this before, but Firebug has a new beta version too, which means that it works in Firefox 3 beta 4.  Grab it from the releases page under the Firebug 1.1 Betas heading.  Possibly the single most useful Firefox plugin for me, the fact that it wasn’t working in the beta releases of FF3 was what was stopping me from switching to the beta. No more excuses now, the Adblock Plus plugin even works.

Mozilla has released the 4th beta of the upcoming Firefox 3 browser.  Check out the review of the new beta by Mozilla Links.  Updates in this release:

• Improvements to the user interface: better search support in the Download Manager, ability to zoom entire page or just the text, continuing look and feel improvements on Windows Vista, Windows XP, Mac OS X and Linux.
• Richer personalization through: location bar that uses an algorithm based on site visit recency and frequency (called “frecency”) to provide better matches against your history and bookmarks for URLs and page titles, as well as an adaptive learning algorithm which tunes itself to your browsing habits.
• Improved platform features such as: support for HTML5’s window.postMessage and window.messageEvent, JavaScript 1.8 improvements, and offline data storage for web applications.
• Performance improvements: changes to our JavaScript engine as well as profile guided optimization resulted in significant gains over previous releases in the popular SunSpider test from Apple, web applications like Google Mail and Zoho Office run much faster, and continued improvements to memory usage drastically reduce the amount of memory consumed over long web browsing sessions.

There’s a link to the download site at the bottom of this page.

It has also been announced that there will be a 5th beta release, with the code freeze on the 18th of March, which means the beta should be available around March 31st. Or they may release it on 1st April just to screw with everyone
