High CPU Usage--When loading a previous session, and especially on a certain site...

Edit Subject

Ghostery 2.5.3 in Iceweasel 3.5.16 (Debian 6.0). 64-bit OS.

When visiting the "Gardeners Forecast" page on weather.com for my area with Ghostery enabled, the page takes a *very* long time to load--about a minute and a half (!). Bringing up the system monitor, both cores of my dual-core processor are being used constantly at nearly (and up to) 100%. No other browsers do this.

A while back I originally deleted my entire Firefox profile directory thinking that was the problem and started re-installing all of my extensions, one-by-one, and had no problem with the site. Problem solved! I *thought* I re-installed them all, but I must've missed at least one...

Just earlier I noticed that the problem started occurring again, and I thought... "wasn't there an extension I just installed recently?," and I remembered it was Ghostery. So I disabled Ghostery, restarted the browser, and went back to the page--it loaded much, much faster.

When restoring a browser session with many tabs open, even after all of the pages have been loaded, Iceweasel (presumably Ghostery, technically) takes a ridiculously large amount of CPU time (and for several minutes), but this is the only site that seems to royally screw with the Ghostery extension (and suck resources) all on its own. It looks like in general, Ghostery could use some serious CPU optimizations and fixes... other than that, functionally, it's a very useful extension.
