What is Firefox doing?

If one watches Firefox's CPU consumption, one can see it consuming large amounts of CPU even while it's not being interacted with. On lower-spec computers, this can cause performance problems that significantly affect other applications.

"After opening Firefox, it might be updating bookmarked RSS feeds. Using, for example, the Live HTTP Headers add-on, you can see that and any other traffic, even though it might seem nothing is being downloaded.

(And as a side note: if it's slow then vacuuming the database that holds the bookmarks and visited sites might help.)"

"Look at your pages. Flash and animated images seem to be driving my Firefox instances. A lot of pages that used to be static seem to be adding Flash.

The other indicator of CPU usage I look for is the speed the fans are running."
