Trunk build from today (200600527): 1. Go to www.idg.se 2. Watch the process hang for a very long time. After about 7 minutes, it unhangs. This is sweden's biggest computer site.

This is a snapshot of what functions are called when the app hangs.

I belive this is a dupe of bug 338839. The patch in bug 335251 makes idg.se work for me.

It is indeed the same as I wrote in bug 338839. It looks however that this bug has been around a while and looks as it is related to Gecko 1.9 as described in bug 335251. IDG changed something in their code in connection with some problems they had a few days ago, confirmed by a phone call to their web development. So this change they made, suddenly made this bug visible I tested an older trunk build (2006042618) , and indeed it fails on www.idg.se This bug is visible in Firefox and Seamonkey trunk builds, in Windows and in Linux. Firefox 1.5.0.3 is not affected.

I can confirm that the proposed patch in bug 335251 works for me (Seamonkey-Linux FC5 -GCC 4.1.0).

also looks like resize or even invalidation trigger redownload at that site in FF
