Details

Everytime I view an image just FF hangs, sometimes for over 10 seconds.

I've tried a new profile, safe mode without all extensions, and have excluded those possibilities. It is also not the webserver, I've straced that one as well, it's really firefox hanging with 50% on the (dual-core) CPU. 

When I view the process using Process Explorer, this is the stack from the firefox-thread I regularly see:

ntoskrnl.exe+0x5909
xul.dll!XRE_GetStaticComponents+0x13b5
xul.dll!XRE_GetStaticComponents+0x2d0b
xul.dll!gfxTextRun::GlyphRunIterator::GetStringStart+0x2286

Sometimes it's this:

Or this (this is from clicking on another tab):

Always the fetchGlyphExtents() at the end. I have tried moving some large-ish fonts away from c:\windows\fonts, and, besides a less nice firefox interface, have experienced only *more* delays.

Anyone able to help me debug this?
What Firefox version are you using? On what Operating System? Is there any reproducible way for this bug?
Heh, as if i remember the exact version after two years ;) I've got no more information than already in the bugreport, sorry. Can't remember seeing it anymore, either. Probably got fixed by an upgrade of Java...

Thank you for trying to help, though.

I'll close this.
