I've discovered that I can't reproduce this bug in Firefox 3.0

Can't reproduce, but I have current trunk, and I'm on Mac. Martijn, do you see this? Geoff, just to make sure, are you seeing this in safe mode too?

Yeah, I'm seeing this a high cpu usage of 1s or so, but not more than that in current trunk build. Older builds don't show this high cpu usage. This regressed when bug 99457 (word-wrap) got fixed.

Ah, yeah. That could do it. We should figure out why it takes so long on Geoff's setup.

Geoff, what computer do you have? What cpu? How many MHz?

Yes my computer is on the old side (850MHz PIII), but I've just timed the test case and it took about 45s at 100%. That's more than just an old computer causing it. Same thing happens in safe mode.
