Windows 7: Firefox CPU Usage Spikes

Firefox CPU Usage Spikes

I recently installed Firefox 3.6.6, and ever since I have been getting huge CPU usage spikes -- up to nearly 50% on one core. These spikes occur about once every ten seconds. When the spike occurs, any action in my browser is delayed a second or two, resulting in annoying lags during scrolling and typing.

I already changed the browser:sessionstore:interval setting in about:config... anybody have any ideas what else the browser could be doing every ten seconds that would produce this aggravating lag? Thanks!

I've got specs similar to yours, and I don't have this problem with Firefox. Hmm... Since you "recently" installed it, you don't have any addons yet, right?

Oh, I have plenty of add-ons. I should have said I recently updated Firefox to the 3.6.6 version. I am hoping to avoid the disable-add-ons-one-by-one-all-night-long slog... I've been through that too many times in the past for it to be fun and informative anymore.

Actually then I'd just ask you to post what addons you have, cause one of them could be causing the problem. It's possible we could eliminate many of them as potential causes just by looking at what they are/do.

I have Adblock Plus and I don't think it does any regularly timed actions. Tab Mix Plus does have a session restore feature, when you installed it it would have prompted you to pick either its session restore, or Firefox's built-in session restore. I have never used the addon's session restore, so if you picked that one that COULD be the culprit. Cooliris is also a possibility. I'd say to try and deactivate those two, one at a time, and see if either one is causing the problem, since they seem like the most likely. If not, we'll try to find a more in-depth way to determine the cause without testing each and every addon.

Thanks for the help BCXtreme. I kinda figured I'd be doin' the disable add-on shuffle tonight... sigh. I'll start with those two. Thanks again!

I think the problem was caused by MeteProducts Integration plugin. After I disabled it, the clockwork spike disappeared. I'm not really sure what that add-on was trying to do every ten seconds; it doesn't seem to have any kind of session store function. It was only supposed to automatically check for updates to apps.

I'll add an update here if I find anything further.

Hmmm... this is odd. I thought MetaProducts had something to do with Software Informer, but it doesn't. I don't know why I had MetaProducts Integration plugin installed.

I would guess the freeze was due to the checking for updates, if that is indeed the addon responsible. And no, that should by no means be the way it functions. Someone obviously did not code that plugin properly.

So, unless you have one of MetaProducts' programs (Mass Downloader, Offline Explorer, or Inquiry), that addon was checking for updates to software you don't even have. Come to think of it, that may have caused the CPU spike; the plugin trying to look for a non-existent program.

Darn. The spike came back. I left the browser on all day and the spike began small, but kept getting bigger until it was as annoying as before. That is going to make it harder to track down 'cause it doesn't seem to happen immediately... it seems to build over time. I'll play around until i figure it out.
