Addessing Wmode Crashes

Firefox 3 is the first Firefox release for Linux that includes windowless mode (wmode) support. Unfortunately, there was a crashing issue related to wmode that a lot of people testing Flash Player 10 beta 2 have encountered, and on fairly major sites.

Great news: Thanks to the Firefox team, this issue has been solved. The fix has made its way into the Firefox nightly builds. You can download them at http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/.

The first build I know of that contains the fix is for 2008-07-08. So start with that one or later, until the next formal Firefox release. Ideally, wmode-related crashes should now be entirely Flash’s fault. But please, before reporting such crashes, be sure (using the About Firefox dialog) that you actually are using one of the very recent builds. And it wouldn’t hurt to be certain that you’re using the latest beta of the Flash Player by checking the “about:plugins” URL in the browser.

    Great, thanks for the commitment!There is still something very irritating about Flash in Firefox: https://bugzilla.mozilla.org/show_bug.cgi?id=78414. Is there any chance that you can collaborate on it too?

  2. What about 64 bit ? …

    I can confirm that it works without crashing sites in the latest firefox trunk. However, when there are wmode objects in the page, CPU usage spikes to 100% and the pages become slow and unresponsive. My setup is:Ubuntu Hardy 8.04.1ATI radeon 9600pro (RV350)using open source radeon driver version 6.9.0Pentium M 2.0GHz

    Great post Laurent. I now have a better understanding of why asiego closed his blog.@RotislavSWFAddress rules. Thanks for all your hard work.

    Is there anywhere to download the old beta? Beta 2 is crashing all the time and uses up an entire CPU core any time any flash content is on screen, and I stupidly don’t have a copy of the old one any longer.

  7. In case anyone hasn’t reported this before, Firefox 3 with Flash Player 10 Beta 2 crashes on lykkeli.com. I’ve tried with FP9 as well and it loads correctly.I’m using Ubuntu Hardy on a fairly recent machine (Core2Duo 2.1 Ghz with 2GB Ram). Please let me know if more details are needed.

  8. After a fp10 reinstall, lykkeli.com started working again. However, i had tried a lot of times before uninstalling it without any success. so something might been going on.

    The “next formal Firefox release”, version 3.0.1, has arrived. However, it was built on July 3, so it doesn’t contain the fix from the 2008-07-08 build. [ True. Maybe the next formal release. -Mike M. ]

    Just in case anyone is looking for prebuilt xulrunner packages with the patches from https://bugzilla.mozilla.org/show_bug.cgi?id=435764, you can find them here:http://ppa.launchpad.net/sniperbeamer/ubuntu/pool/main/x/xulrunner-1.9/I've installed xulrunner-1.9 and xulrunner-1.9-gnome-support over the top of a fresh Ubuntu 8.04, and the problems with FP10Beta2 have gone. 🙂
