Firefox 3 – Return of the Beta 3

Firefox 3 Beta 3 is released out for testing purposes. Are you getting excited yet? Here are some things worth taking note of in the newest Firefox release:

  • [Improved in Beta 3!] Speed: Major architectural changes (such as the move to Cairo and a rewrite to how reflowing a page layout works) put foundations in place for major performance tuning which have resulted in speed increases that continue to increase page drawing speed in Beta 3. This release also features over 90 changes that improve performance over the previous beta.
  • [Improved in Beta 3!] Download & Install Add-ons: the Add-ons Manager (Tools > Add-ons) can now be used to download and install a Firefox customization from the thousands of Add-ons available from our community add-ons website. When you first open the Add-ons Manager, a list of recommended Add-ons is shown.
  • [Improved in Beta 3!] Memory usage: Over 350 individual memory leaks have been plugged, and a new XPCOM cycle collector completely eliminates many more. Developers are continuing to work on optimizing memory use (by releasing cached objects more quickly) and reducing fragmentation. Beta 3 includes more than 50 improvements to memory use over the previous beta.
