Full Article Attached Some Significant Improvements

Saturday December 11th, 1999

M12 is right around the corner, and will boast significant improvements in the responsiveness and layout rendering times of the application.

First, Dave Hyatt has checked in some changes which do "memory recycling of all layout frame objects". This recycling seems to be the cause of significant improvements in the responsiveness of the UI. In #mozillazine, I heard "nearly as fast as 4.x" (on a P90 with 16M ram; I think that it's as fast or faster than Communicator 4.x now, at least on my P2-450). Menus and context menus now respond smoothly and quickly, the sidebar expands and contracts quickly (albeit with some bugs, still), and new windows pop up much faster than before. These improvements have been noticable on Windows, Linux, and Mac platforms, but to different extents. You will just have to try downloading a build for yourself!

Next, Vidur Apparao added changes that allow you to tune the incremental reflow. A number of people complained about how the incremental reflow changes of M11 were a good idea, but they were interfering with UI responsiveness as a page loaded. These tuning options address that problem, but even more improvements are expected after the M12 release. To try out the tuning for yourself, download today's build (December 11), and then follow the instructions on the next page (click "Full Article..." at the end of this news item). These options are only for people who are comfortable editing preference files. If you're not one of those people, these options should be enabled automatically at M12's release, so you'll be able to try it out then.

I would suggest picking up today's build when it's available (December 11), as it should contain a fix for alert-box buttons that you'll want to have. You can get the latest build from our builds page, or the nightly builds directory.

Remember, as always, these builds are not for the casual user. None of the software is guaranteed to do what you expect. MozillaZine makes no guarantees about the stability of these builds. Download at your own risk.

I can't tell a significant boost in Mac performance from a week ago, although the preferences dialog looks a lot better, I thought for a second I was using Communicator's. One thing that has happened recently is that when I use the Mozilla Installer app to convert my NS 4.61 profile, it converts it but then says there is an illegal character in the Mozilla User Preferences and the profile is unusable. This is strange because it converted the same profile about a week and a half ago fine.

Also, is the Preferences->Appearence->Themes function supposed to be working. I can't see any changes.

Finally, ANY developers out there PLEASE, PLEASE add a keyboard shortcut for View Page Source (Like Apple-U). This is something that has been missing for a while. If a big feature of IE 5.5 is "Print Preview" you could probably put a new version number on Mozilla if you add this feature!
