Bug Description

Binary package hint: firefox-3.0

This particular website http://www.ouest-france.fr/, an important French newspaper, makes Firefox and Xorg using all the CPU ressources. This makes my old laptop impossible to use while reading this page. I also tried with an installation of Hardy with Vmware on a more powerful machine and it also uses all the CPU. The

There is probably a bad scrip in this page but this problem does not occurs while reading this page with an other browsers like Konqueror and Opera.

I can confirm this and it's not the only webpage affected by this. It's probably caused by the crappy flash plugin.

Changed in firefox-3.0:

Apparently, it is not related to flash plug-in since I don't have it installed on my computer and I still observe the same problem. I would guess it is a problem with the JavaScript interpreter. The same problem appears with Firefox 2.0.0.14 on Gusty. I will try to see if the same behaviour appears on Mac or Windows.

Sometimes firefox freezes totally for some seconds and uses 100% cpu if I only have some launchpad pages in tabs opened

This bad behaviour of Firefox also occurs with the web site http://www.ouest-france.fr/ with Firefox 2.0.0.14 on Mac and on Windows. So it is not an ubuntu specific bug. The very bad point is that concurrents of Firefox like Opera, Safari and IE7 don't cause the CPU to run like this.

I have a same problem also with web site http://www.griddlers.net with FireFox 3.0.

Similar problems are reported dew to Java or Flash.

But I disabled both Flash player and Java plug-ins, problem remains.

The website looks not heavy at all.

Chek out that web site too, please.
