I seem to get random spots where browser starts using 95% of CPU time. This is with build 2001042013. I'll add more when I find a way to reliably reproduce it. So far I've noticed it 2 times in the past 24 hours.
Is this happening when a dialog box is waiting on the screen? I notice that under Linux that Moz has pegged the CPU whenever it puts up a 'do you want this image / cookie' prompt. That's been happening practically forever, so there's probably already a bug filed on that problem.
No, this has only happened with the 0420 build (previous was 0316). I noticed it because the system seemed more slugish than usual, so I loaded top. dnetc and Moz were fighting it out, with Moz winning. When I loaded my mail client 20 minutes ago, I noticed the same effect. Again it was Moz. 3 windows open, no dialogs, nothing loading. Just spinning away and away at the CPU.
Steps to reproduce with build 2001042708: Load http://www.gibsonhax0r.net/media/winblows.html Right click image, choose "View Image" Watch the CPU usage peg. I think this is related to the throbber not stoping, despite the "Image loaded in 0.16s" being in the status area..
Another way to reprduce (including in 0.9!) is to look at an image, click back, then view the image again (like in a dir of images you are looking at). I think it's some interaction between newcache and libpr0n, since you have to view the image once before the CPU is sucked.
