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.

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.

I launch Firefox and access the website. The destination website is simple, rich, regardless of type. A few seconds after the website is displayed, the number of revolutions of the power supply fan increases and the sound of the fan increases. And although the temperature of the power supply unit does not change greatly, the rotational speed of the fan is nearly doubled. As soon as I close the Firefox window it starts to slow down.

I endure the noise of fans and use Firefox for 20-30 minutes continuously. At this time, even if the user does not operate it, the fan rotation speed maintains the high-speed range just by leaving the window open and leaving. As soon as the window is closed, the speed drops.

This doesn't happen with other web browsers. This happens even if I recreate the profile.

--- Firefox 66.0.5 (This has been confirmed to occur from 66.0.), macOS 10.14.5, Mac Pro 2010

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

Hello everyone:

I got this macbook

13" early 2008 Processor 2.4 GHz Intel Core 2 Duo Memory 4 GB 667 MHz DDR2 SDRAM Graphics Intel GMA X3100 144 MB Software Mac OS X Lion 10.7.5 (11G63)

Firefox 39.04

I have personas and classic theme restorer installed so I can have the tabs not be on top, and a non moving squirrel picture on the frame. I got the computer used last year, maybe the year before, It's been lightning fast, but I use it for business social media stuff, 30 twitter pages open to monitor hashtag pages. while loading other pages I get script slow errors,

The computer gets HOT the fan is beginning to make noise because it always runs. Even if I open one ONE ebay page (in FF) and let it sit there, it will within 20 seconds stop responding and get HOT. As I write this on safari the machine is running fine fan at slow idle, room temp 82 Humid no A/C.

The computer was wiped, new OS NEW FF 39 new when I set up this machine. When using FF along with Safari or Photoshop 12 I think, they can all be on and working, but FF will freeze, the others will work, and the fan runs so fast it lifts the machine off the table.

I have read and tried so many of the message board fixes, including the about:config tell the flash player not to load in each page repeatedly if not used, no help. I take a screen pic, and then restore it to original if it don't work. Something about a plug-in container. Activity monitor also says FF uses more than 450MB ram Really….? Normal….? 1 tab…? Well safari has 418 MB …..

Done some of the fix it's on the FF help pages, turned off plugins safe-mode still spins up the turbines. Not installed a new FF as there does not seen to be a real fix in doing that from what I have read.

Had this machine for a while, use to work fine, lightning fast, no fan unless watching a movie, now I don't even try using youtube…..

No other add-ons readers, tool bars etc. installed. Ever. I basically do the same thing all the time. Also for some reason even though flash is always manually updated, videos even GIF's on twitter now place an error in the center of the post "your browser does not support video playback"

How can the dam thing use more than 100% of the cpu resources anyway……? WTF ???? Using some of the CPU from tomorrow ????? Some kind of payday loan FF has for the CPU ????

Load_payday_CPU_firefox_interest-rate_120%_  :true  ??? Where is it ?


I can load other info if anyone gives me an idea where to get it terminal, activity monitor, air traffic control, what have you.


Thanks.

I have post this questions a week ago but there is no response of my questions. I re-post it and hope someone could help to resolve the problem. The firefox v.65 crash , usually after 3o mins, when I have the new brought photoshop elements 2019 program running in the background. After crashed I try to restore the tab. However, firefox crash again right after restart and restore the tab. If I keep trying to restore the tab. The firefox has no response and freeze. A error message come out " video driver failed to restart ....... Sometime the computer get into blue screen and die. i find that the problem also happen with Microsoft Edge browser too. I google the possible issue of the crash and get some information regarding the crash. It may be cause by the photoshop element face detection feature use too much memory to run the program or the program has memory leak problem that cause firefox crash.

I did check my computer RAM memory and PC window system files. they did not show any error. I refresh firefox and reinstall my video driver. However, it make no change of the crash situation. The firefox crash and Blue screen die issues only happen if I run my photoshop element and premier 2019 program at the same time. Adobe support said that it was not photoshop element program problem for the firefox crash.

I want to find out what is the root problem of the crash and how to fix it. I also want to know any known issue firefox crash assoicated with photoshop elements program.

When using Firefox and loading multiple tabs, it can be very slow, and even freeze occasionally. Considering the resources I have available, why is this? Are there configurations I can change to allow Firefox to make full use of my processor, RAM and broadband speed?

Also, when I download files etc. from a site, I'm limited to only 4 at a time, and they rarely download faster than 1Mbps, usually only around 200Kbps. Is there a way to increase the number allowed, and to increase the top speed per download?

Thanks.

This has been happening for a couple of months now. Firefox has been crashing ever so often, and because it usually happens when flash content is being run; i.e., a video or a web game. Another reason that leads me to believe this is Flash is that before I had this problem, flash would eat up my CPU, and I would be peaking at 100%! Another problem that I am having right now: I can't have two Flash things actively running at the same time, or else Flash will crash, for example, a video and a game. Ads don't seem to crash Flash as often, but it will sometimes happen, especially if there is a lot of moving content. Anyways, you can look at some crash logs to try and figure out what is happening with my issues.

Fan runs high & hot watching youtube videos. Have new macbook pro retina 15" mid 2015. 2.5 GHz intel core i7. Started happening after second to last Firefox update. Updated to most current thinking it would be fixed. It doesn't happen if I use Safari. Apple support senior lead tried to resolve issues. Sorry, I'm not very technical. Tried shift, control,option start. Tried option, command,R,P start. Tried logging on as a new user. Tried so many options, I can't remember them all. Uninstalled, reinstalled,and uninstalled again. ran disk repair(?). Followed Firefox troubleshoot all the way to the end. Started in Safe Mode...everything. She told me to contact Mozilla to see if you had any answers to my issues. I also had issues last week with Firefox crashing 3-4 times in a row while watching youtube. I sent reports to Firefox. I hope someone can help me. I prefer Firefox to Safari! Thank you!

Hi,

My first time here, just recently switched from Chrome to Firefox, but seems like it's a bit problematic. Version 70.0 worked fine, but ever since 70.0.1, Firefox starts crashing (randomly). 99% of the time there is no error message, the browser just crashes(closes) and that's it, no crash report, no error, the only thing I can do is to restore previous session. Usually, after crashing, it will crash again 2-3 times upon opening the browser, until it will finally work...for a while. Rarely there have been errors, saying the same thing - memory could not be read (attached in the post). Does not happen with any other browsers. All my drivers and software are up to date, memory is OK, (did windows memory diag and memtest86), hardware is okay, tried disabling plugins and hardware acceleration, still nothing. All that ever since 70.0.1, before that it worked fine. Is it just me or anyone else having that problem? If any additional info is needed, let me know.

Dear Firefox Support,

I've noticed a huge spike in Firefox Quantum's memory usage recenlty imgur.com/XCDtJy8 What do you think is the cause for this? Didn't install any new extensions or plugins, already ran scans with various antivirus/antispyware & registry fixer tools, they didnt detect any malware & fixed all registry issues. I also already cleared cache & cookies, saved data, refreshed & unistalled/installed Firefox Quantum multiple times, without improvement.

Normal usage until recently was about 300-500MB total, 50 MB per subprocess. Now is about 500MB PER subprocess (around 3-4 GB total) all the time. Is there a way you could look at some data or files from my Firefox installation to determine what is the cause for this memory usage increase? Maybe looking at the "about:memory" information to see what is making the processes use so much memory? I added the troubleshooting information to this question, and am willing to provide any other information you deem neccessary for troubleshooting purpose.

Thank you so much in advance, looking forward to hear from you!

I use Firefox on Windows and Firefox tries to use too much of my system's RAM. I know this is for performance reasons BUT there is very little performance gain. This behavior is fine for users who only run Firefox and little else. BUT I use other memory intensive apps not only Firefox so Firefox using up lots of my RAM is very bad for my use case.

On a system with lots of RAM when I use gmail and Facebook on Firefox the firefox processes can bloat to more than 2.5GB! And it actually seems to start getting slower at that point.

But if I run Firefox in a Windows Virtual Machine with only 1.5GB RAM and start using gmail and Facebook a lot the largest firefox process only gets to a max of 750MB. So that is proof that Firefox can actually work with less RAM without crashing.

How can I get Firefox to behave as if the system has less RAM (e.g. just set a max RAM limit) without to resorting to running it in a VM? I have tried stuff like Process Governor but Firefox tends to crash when it hits the limit instead of running the GC. In contrast on a virtual machine with less RAM Firefox doesn't seem to crash and just uses less RAM.

Is there also a way to get Firefox to automatically do what the about:memory "Minimize memory usage" button does, when it starts to go past a memory usage threshold?
