Every time I start firefox after recent updates, top shows it periodically taking up to 50% of the CPU even if I'm just looking at a simple page of plain html (no scripts, not even any images) on my local web server.

This is ff 13.0.1 on x86_64 fedora 17.

Any clues? Anyone see anything similar?

Basically the same thing here -- FF 13.0.1 on fedora core 17 x86_64 -- except that CPU usage isn't maxxing at 50%; it sometimes climbs a bit above that.

Haven't started my i686 machine to see whether the same behavior occurs thereupon.
