FF 34.0.5 hogging CPU like crazy

Posted

Since I upgraded to v34.0.5, FF has been intermittently freezing and consuming all my CPU, making it a PITA to use. I never had this problem with previous versions. Anyone else getting this?

Possible Mal-Ware Scan For Macs {web link}


Type about:addons<Enter> in the address bar to open your Add-ons Manager. Hot key; <Control>(Mac:<Command>)<Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is detective.

Thanks for your reply.

Firefox uses a lot less CPU in safe mode, regardless of whether hardware acceleration is enabled or not. The problem I'm having might be due to a compatibility issue between FF and one or more add-ons. However, my add-ons are so crucial to my use of FF, that I might end up having to downgrade.

Thanks FredMcD :)

No malware here, thankfully. However, I removed a few non-essential add-ons, and things seem to be running more smoothly, for now. I'll report back if FF reverts to coughing and spluttering.

Note that all of the suggestions involve blame on everything but FireFox, my cure was to revert to earlier version that did not cause this problem.

I have the Same Issue.

I have nearly done 20 things "Recommended". From turning off hardware acceleration and loaded Memory Fox to no avail.

I have a 4 core 3.8 GHZ CPU with 8 GB memory Win 8.1 and shocked that Firefox wants to freeze and lag near only 1 GB when the CPU is only 31% and Memory around 33%

Yes I checked for Malware and virus , I do that week the most I get is just tracking cookies.

I can have it lag and lock up on 3 tabs, 2 Twitter and 1 Facebook.

Many times this happens it makes my whole PC lag too. And before you ask I have had my memory checked. I can load several programs at once to try to bog down my CPU and memory and I get nothing that Firefox is doing.

I have also had Firefox cause 3 times now the BSOD. Where it says "Not Responding" and nothing is responding on Window either.

I monthly defrag my drive and have 110 GB free on my drive.

I clean the cache and more and nothing.

Oh I forgot to add beside it freezing every time when it gets around 1 GB memory, when it lags and freezes, the CPU and Memory still does go up and down under Firefox. It does but slowly.

(The middle picture below that is Firefox in the Background it didn't say "Not Responding" but nothing was working lost toolbars and twitter page went black.

I am having the same issues you are. I have spent an insane amount of time trying to figure out how to solve these issues and nothing works. I've tried everything! I think it's this version of FF. It's not my computer or my add-ons. Hopefully this will be corrected soon.

Hold up I have No Issue with it freezing or locking up since I loaded Ghostery. I notice it lagged bad when third party tracking cookies were being loaded. Yet now my issue is ghostery causes your Option panel to be blank.
