does your firefox/thunderbird use excessive cpu/memory/file access?
 

Every once in awhile my computer will slow to a very annoying level. When this happens I take a look at my task manager and sure enough either Firefox or Thunderbird is using like 99% of computer power and in excess of 100 megs of memory. If I kill the process then my computer runs just fine again.

I looked through the mozilla forum and bugzilla and this is referenced, but I'm wondering how widespread the problem is. Do you guys have any trouble or am I just an unlucky one with this bug?

Every now and then this happens to me too. I put it down to poor memory managment by Windows and not a Mozilla problem as it happens to any app I have open for more than a few days (like iTunes).

How long do you leave your computer running?

I used to have this if I didn't re-boot at least once a day - prior to that I would leave my computer on constantly.

With me, 24/7. I just open the taskmanager once every day or 2 and kill a bunch of stuff.

Yes, this happens to me daily. I look at the task manager, and Firefox is using over 100K! Rather annoying.

100k, no way!

Seriously, I find that simply quitting and restarting firefox will do the trick. The memory/cpu hogging issue seems to me (though I'm not certain) to be related to plug-ins like Java, Flash, etc. Closing the browser also unloads the plug-ins and seems to put things back to normal.

yes, this can happen
 

this CAN actually happen, but most usually when using TABed browsing in FF. Every new tab consumes about 10K more in memory. Sometimes a bit less, sometimes more. problem is, when a window is opened that runs the JAVA engine, that boosts it up about 40K, so 20-30K base, plus 10K a window and then BOOM 40K for a window that is running JAVA.

I have had well over 100K on FF sometimes, I know then I am opening too many windows. I try to keep it to under 10 open windows at a time.

I have noticed that firefox uses more cpu than it should if you display a page with graphics that change, especially if the macromedial flash player is active.

I've gotten used to hitting the 'home page' button when I leave the browser idle. My home page is set to a blank page.

I don't do very much tabbed browsing.

Methinks some people are confused between Kb and Mb. I WISH Firefox would only take up 100k :D

yeah
 

yeah, when I say 40K, i don't mean 40kb, I mean 40,000kb, or 40MB. Just dropping the kb.

So it should read 40Kkb

or, too much

Methinks you should venture outside and get some fresh air once in a while!

I keep quite a few FF windows open, I always run over 100 MB. Right now it's 113,600 kilobytes = 110.9375 megabytes (thank goodness for Google calculator). Of course it's not so bad, 'cuz I'm running with 1 GB of memory! ^ ^

O, TIR!

While on this topic, is it possible to block Macromedia Flash and Shockwave from running, or even loading, from ad sites? That's one function that I'd love.

the ....... extension will do that.
