FF uses 100+ CPU on my otherwise totally fast up-to-date MacBook. This, despite doing all the fixes suggested, repeatedly.

It has gotten so bad that it constantly overheats my Mac, causes my fan to go on full blast non-stop, even when it's in the background, so I basically have to stop using it.

Mozilla needs to get serious and overhaul this heavy-use browser.

bp-246727e7-eff9-41f4-b6dc-d906c2151115

Firefox has been crashing when I open it for over a week now, and I really miss it. The problem started when I updated the SilverLight and Adobe add-ons/plug-ins. Firefox has never opened since. I have re-installed it, un-installed and then re-installed it, tried running it in Safe Mode, tried installing it in Safe Mode, tried re-installing it after deleting the C-drive folders, and even tried uninstalling Silverlight and Adobe and re-installing Firefox without them even in the system. I tried re-installing them and then re-installing Firefox--nope. Finally, I went back to restore point in my computer from a week before the problem.

When the computer was restored, Firefox was there--version 41-something (Oddly, it was set to upgrade itself), which wouldn't open because it could not find a file called XPCOM. I can't get into Firefox to reset it to the factory settings, which I'm sure include XPCOM.

What now? I love Firefox, and I'm not ready to be done with it...

When I navigate to www.pcmag.com on my Surface Book 2. FF will hang or crash. I do not have this problem with other browsers on my laptop. Is this a known bug or do I need to update something.

I am running the latest FF version with default settings, the only add-on is BitWarden.

I've tried both version 40 and 42. Every time I try to load a webpage, Firefox quits responding part way through. I've gone through add-ons. I went through all the help articles and nothing worked. The problem started after installing Windows 10 and often happens on Politico and Fox News. I have tried uninstalling and reinstalling. After the uninstall I scanned the registry with ccleaner

What has happened with Mozilla? A month ago, there were no problems when watching stream video 1080p 60fps. But now it is impossible to do it: constant and long freezes. I have noticed that CPU load is almost 100% when watching stream. I have recorded the system parameters for 10 minutes for the same stream via Mozilla and Edge and the difference is great (see the attached files). I do not know what parameters were a month ago for Mozilla but definitely I never noticed any problems. Hope this info will be helpful to fix the problem.

Firefox will not start in normal mode nor in safe mode. It crashes instantly to the crash reporter, right after opening.

Everyone I know, and many reporters, here, are having memory leak problems. Hopefully, this will be repeatable, for you: - Run ff, with a single tab, and go to: weather.com, - run Task Manager, and watch cpu head toward 90%, and memory all get consumed.

This is on a Win10 box, clean install, with new install of FF57, and no add-ons. Same issue on Win7 box, which has worked fine, for many years, until 57 came along.

Firefox (latest version, 43.0.4) is causing my HDD to run between 98% and 100% all the time and making heavy CPU demands too, fluctuating between 30% and 70% CPU being used by Firefox. I've tried clearing my cache and cookies etc. No change. And I've tried starting Firefox in Safe Mode. Again no change.

Tried disabling my Internet Security software (McAfee). Again no change.

Google Chrome doesn't do this and Microsoft Edge doesn't do this, so it's definitely associated with Firefox.

Running a PC with Windows 10 (64-bit Pro version 1511 with all subsequent updates installed).

After stopping Firefox in Windows Task Manager everything returns to normal. (0% HDD usage and 4% CPU usage.)

Help!
