Firefox 3 is so slow and crashes my entire computer

Sorry- I was on a different profile and sent the add-on list from there. I deleted my previous list but you saw it before I got to it!!

Here is the list for the profile I usually use:

Application: Firefox 3.0.1 (2008070206)
Operating System: Darwin (ppc-gcc3)

- Adblock Plus 0.7.5.5
- AirSet Connector 1.0.2
- Better Gmail 2 0.6
- Cooliris Previews 2.6.4
- Delicious Bookmarks 2.0.95
- Extension List Dumper 1.14.1
- GMarks 0.9.9
- iGoogle Sidebar 1.3.6
- Shareaholic 1.4.1
- StumbleUpon 3.26
- Taboo 0.5.5
- Twitbin 1.5
- TwitterFox 1.6.1

You can have twitter add-ons without logging into them. I have two different twitter accounts so if I wanted to run both programs using different accounts, I could, but I usually don't. Firefox runs slowly whether I run both, either or neither.

By the way, two sites which seem to take Firefox 3.x over the edge are MySpace and Gmail. While those two sites aren't the only problem, they are two I can definitely point to as often causing Firefox to hang.

?? I have never stated what I would not do.

The gmail add-ons don't stop the problem I have with FireFox running slowly and crashing, although disabling them seems to cause me to have fewer problems with gmail loading in standard mode - but that's the only difference. I still have had to reboot my computer regardless of whether the gmail add-ons are enabled or whether I'm using gmail at all.

As for following your advice about enabling the add-ons one by one, I have done that before, and am happy to try it again since FireFox 3.0 has been updated a couple of times now, I think. However, I noticed that Firefox ran slowly without any add-ons at all when I first downloaded it.

I will let you know how it runs with no add-ons.

I have now run FireFox with no add-ons for several hours. I get Adobe 9.0 script errors that cause FireFox to slow down and hang. windowserver cpu percentage also gets into 80% and 90% which causes the computer to hang, leaving me no choice but to reboot. It appears that the Adobe and windowserver issues are related but I don't know if Adobe always causes the windowserver problem.

That sounds exactly like how Firefox acts on Ubuntu. The problem arrises from websites using flash content with wmode="transparent" (you cannot see the flash player in Gmail - it is used only as a sound API).

Basically, you need to turn off chat in Gmail, or use Safari.... :P
On linux I just removed the Adobe flash plugin, which completely solved the problem. Flash is crappy anyways ;)

Also, when firefox hangs, use the keyboard shortcut to open up Force Quit - the Mac menu will freeze, but you can still run Apps. Also try clicking the desktop or command-Tab

Hmmm...I've never had a problem with the chat in Gmail, though- in fact I use it (google chat, right?) with no slow-downs or anything in FireFox.

But the problems described with Ubuntu seem to be the ones I experience often with MySpace and other sites. If I remove the Adobe flash plugin, will I just not see flash items on sites, or will apps on my computer itself be affected?

Regarding Force Quit- that doesn't work for me when the slowdowns and freezes occur, because even Force Quit doesn't work at that point. I think it's because whatever happens while I'm using FireFox also affects windowserver, which means nothing works. On rare occasions I can catch the FireFox problem quickly and Force Quit it before windowserver is affected.

I'm not against Flash, I am just absolutely sure that the use of wmode="transparent" is what causes the crash. I've had this issue on multiple installations of Firefox since 1.5, and I have had it occur on all of the common non-Windows Operating Systems.

Also, I didn't recommend the removal of Flash, but the removal of the Adobe Flash plugin. There are more stable and reliable Flash plugins for Firefox on Ubuntu. As a developer, I just make every effort not to use Flash because of this bug, and also because the Flash plugin does not support layering (z-index) on Linux.

Well, my computer died last week. Receives power but there is absolutely no activity- must've gotten fried somehow overnight. The good news is that I am able to get a new Mac laptop. I will add add-ons to Firefox very slowly with the new Mac & OS to see which ones cause problems. Thanks for your help, Thomas, and for your suggestions, developit.

sorrry your computer died. my laptop died 7weeks ago.

I feel for you, duke. I've bought a new laptop (MacBook Pro running Leopard). I'm running FireFox 3 with the add-ins StumbledUpon, Gmarks, AdBlock Plus, Google Notifier, CoolIris, GRAppleDelicious, and Shareaholic. No slowdowns or freezes whatsoever so far!

Do older versions of the Flash plugin work better on non-windows Operating Systems? Please let me know if this is the case, as I am installing Ubuntu on my business machine and would be interested in participating in Flash-based web seminars without crashing Firefox.

Also, I am sad to say that, although Firefox has seen a lot of improvements on Mac recently, I still experience the odd crash when Flash is being used. It seems to happen more now on YouTube, which makes me wonder if it is their issue.

Firefix 3 is rubbish. It continualy crashes and is ridicuously slow.

I HATE it and am going back to Safari

Are you still having this issue? What did you do, suggestion pleaszz-eee.

It is Weds., Nov. 11, 2009. (This is my crew: xp3, firefox 3.5.5., flash10, comcast, facebook, yoville.)

CRASHING, HANGING, SODOM AND GOMORRAH.
This happens to me everyday now. My computer crashes whenever he sees flash, falls over and faints. What a sissy!

Mainly happens when I go to a flash game, like yoville. Games at first work fine, in the beginning, for about 10 minutes, flash being cpu sassy, at 100%. Then the nuclear winter comes, and the game stalls, anarchy then oppression, programs get hanged, animation freezes over, handsome operator hyperventilates, My yoville world comes to an end...or...whatever you want to call it...me, Ensign Hot Damn Goodlooking, is left there, in the comm. seat, floating - dead in the water.

Pre-Nov. 2009, using FF 3.5.4, I would call up taskmanager with The Ctrl+Alt+Det keys, which I use to slap around my daydreaming computer. Now seems to no longer work, unless I call it up before going to an evil flash based program. With the updated firefox 3.5.5., the firefox browser is still freezing and sometimes crashes to holy hell. The only difference so far, is, I can't do much about it, because taskmanager does not come up, when needed, and I have to cut power to the offending bastage. It seems Taskmanager no longer reads cpu running 100% with ff3.5.5, but, to be dumbed down in knowing what programs are running. (ctrl+alt+dlt = moe+larry+currly), withl flash/firefox still hanging/stalling...but cpu showing 12% to 40% usage? I am not, sure what is happening now.

I plan to un/reinstall flash, firefox again, and see who is boss today :O) "My weekly chore".

ahhhhhhhhhh,

ahkinum, emerald city, wa-state

My computer crashes about mins after firefox is installed anyone found an answer? 2009
