Mozilla 1.3 Alpha Released

Friday December 13th, 2002

Mozilla 1.3 Alpha is out! This release introduces shedloads of new Mail & Newsgroups features (including Bayesian spam classification, message views and improved filtering), a new Bookmarks Quick Search bar (similar to the one found in Phoenix) and support for the Back and Forward buttons on the IntelliMouse Explorer. There's also improvements to the DOM Inspector and lots of other bug fixes. However, remember that this is only an alpha release, so expect bugs.

Builds are available from mozilla.org's Releases Page or directly from the FTP site. Check out the Release Notes for more info.

This is a myth. After you launch mozilla the first time, you lose this advantage and it still feels slower after that. The real reason mozilla feels slower is the overhead of XUL. XUL is nearly as fast as native components. However, there are these barely noticeable delays that add up and the slight inconsistencies with the native behavior that users notice.

There are a few moments I always notice Mozilla is slower than IE" going back and forth between pages. When you click back in mozilla, there is a few hundred millisecond delay (enough to notice). In IE the response is much quicker. A similar delay can be observed when clicking links, scrolling, opening new windows, new tabs, etc. It's not so much the loss of time that gets annoying but the awareness that things slow down momentarily.

The mozilla developers have done a great job optimizing gecko (which also handles the XUL). The performance degredation used to be much worse. In fact, I find that the 1.2 and later versions of mozilla are noticeably faster than the 1.0 series. However, IE has been gaining weight. In windows XP there are all sorts of themes and animations slowing down the UI. I think this will become much less of an issue as gecko & hardware become faster.
