I'm finding that firefoxcp isolated web content uses a LOT of memory on my Mac Mini. What can I do about this besides not using Firefox. I like the browser and have been using it since its introduction

Hi, after update 137.0.1 (64-bit) using Firefox with latest Gecko driver 0.36.0 in Python Selenium stalls and fails to initiate drivers without returning initiation errors every second launch, previously this stall without returning initiation errors would happen every ~25th launch. Also when it does successfully launches previously 9 instances used to use about 95% of my 8 GB RAM, now 6 instances use 100% RAM. Nothing else in my system changed besides Firefox update.

Hello, I am running win 7. Yes and Old computer. When the system is running slow I do a task manager to see what might be causing it.

I have noticed multiple Firefox processes running with 0 CPU usage. What are all those for and do I need them? Can I disable them?

On a separate issue I am getting this rendering error. This may be a Microsoft question, but I thought I'd ask. Error in rendering player Error Code: 400-404 Session Id: k6x4392p (Pls: 35a725dd-3aac-4813-8431-159ebc196c01)

Lastly I did contact support about uninstalling two Firefox programs. I deleted the one you said.

Thanks again for all the help, Irv

When opening Firefox, Duplicates open but are unseen. I may have 2 tabs open but my task manager tells me there are 14, sometimes 31. What can I do to stop or get rid of the duplicates pages. if I can't I will have to remove Firefox.

Firefox is running too many processes in the background. You have eliminated access to the user settings to be able to reduce that number. It is using so much memory (two tabs, one window, 1400 MB) it is becoming a nuisance rather than an asset. How do I reduce the number of processes. Thanks

One page of Firefox 115.21 opened and Task manager memory usage for Firefox reports-:

1) 9,956 K 2) 46,288 K 3) 11,564 K 4) 55,268 K 5) 21,560 K 6) 9,996 K 7) 5,516 K 8) 302,924 K 9) 40,272 K

These are ALL marked Firefox and in order on my Task Manager, the Page 'opened' was Firefox help forum ,,,, some memory usage here, is this right????

I have been using Firefox for many years now and I have always been greatly satisfied with its stability, performance and features. However with the last couple of releases something has changed. The number of tabs I keep open and what they are connected to have changed very little over the years. The CPU utilization has never been much but now it has become huge - utilizing multiple CPU cores and running them at 100% whether I am using the browser or not. I have gone thru each individual tab/web page removing it, waiting for a period of time and them re-adding it assuming this was a website coding issue. Nothing changed. So I gave up and move 98% of my web browsing to another browser (Opera) - moving one website at a time until what was left on Firefox was 11 tabs. Finally the CPU utilization went away. I got the latest Firefox version update today, installed it and now Firefox has changed behavior yet again. Those same 11 tabs will not use any CPU as long as I keep Firefox open and visible on screen, but if I minimize the Firefox window it immediately jumps up in CPU utilization. This makes no sense to me.

What adds to all this frustration is I am running on a system76 Thelio desktop. While extremely fast they have a known issue with their somewhat loud CPU cooling fan kicking in too fast when high CPU utilization occurs. Firefox never used to cause the fans to run but now the latest couple of versions cause the fan to run continuously.

Here is a paste from "top" showing the top 2 cpu processes - both from Firefox and the browser is minimized:

416154 greeves   20   0 3796844 612012 260196 R 109.6   0.9 147:49.17 firefox-bin

 My apologies if I have run on with too much info that is of no help.  If anyone has any ideas it would be appreciated and I would be happy to test.  FYI, my OS is up to date, Firefox is up to date, BIOS is up to date, I have restarted Firefox many times and I have rebooted several times.  I thought Mint might be the issue so I loaded Pop-Os and tried it with the same results.  Btw neither Opera or Brave shows the problem.  However I would prefer to use Firefox as I really like the features - especially how it handles tabs and grouping them.

Thanks in advance for any help!

Hi,

there are massive performance issues while playing videos on Youtube while using Firefox. This does not happen with the same video while using edge. The attached video shows the used memory and CPU of the youtube tab from the firefox process manager. This was taken after playing the video for 30s. Letting it run longer resulted in firefox taking up 20GB of RAM.

I think this happens since I installed 138.0 of firefox.

Could you please take a look.

Thanks.

Best regards

firefox 138.0.1 is eating up memory, specifically;

-contentproc -isforbrowser -prefshandle

theres over 20 of them requiring 200mb each

please tell me how to turn this off

thx

Firefox consuming too much Memory, ranging from 1800 MB up to 2000 MB, causing my other programs (most notably Corel WordPerfect) to constantly crash. How do we resolve this?

Have any of you noticed how much resources Firefox use? Task Manager tells me Firefox requires 11 to function using 700 megs of memory. I have 32 megs on board and if I run auto-clicker on Firefox my fan needs to run to cool the processor... This doesn't happen on Chrome. Firefox is my browser of choice... (add-ons)

Hello Team,

I'm working on building Mozilla FireFox on my riscv64 development platform on Ubuntu-22.04, Below is the source and branch from where i'm using the sources.

https://github.com/mozilla-firefox/firefox.git (Branch: FIREFOX_139_0b10_RELEASE)

I'm following the below steps for build firefox:

Created a mozconfig file with the following contents:

mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/objdir mk_add_options AUTOCLOBBER=1

ac_add_options --enable-application=browser ac_add_options --disable-debug ac_add_options --enable-optimize ac_add_options --disable-tests ac_add_options --without-wasm-sandboxed-libraries

Installed dependencies:

apt-get install -y python3-dev curl curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh pip install -U pip ./mach bootstrap cargo install cbindgen apt-get install -y nodejs apt-get install -y llvm-14 llvm-dev clang libclang-dev libpango1.0-dev libx11-xcb-dev libxcomposite-dev libxdamage-dev libgtk-3-dev

Configured the build:

./mach configure

During the build, I encountered an error with Cairo version 1.16.0, so I updated Cairo to the latest version by doing the following:

tar -xvf cairo-1.18.4.tar.xz apt-get install -y meson mkdir build && cd build pip3 install --upgrade meson meson .. --prefix=/usr/local ninja sudo ninja install pkg-config --modversion cairo

After which I executed build:

./mach build

The build took ~14 hours and reached this step:

892:50.50 Compiling gkrust v0.1.0 (/root/firefox/toolkit/library/rust)

However, after about 30 hours, I ran into an Out of Memory issue. I am using a 64GB SD card for the build and have created a 10GB of swap space within the 64GB, but still encountered this error:

[189659.052881] Out of memory: Killed process 52440 (rustc) total-vm:14996824kB, anon-rss:5113116kB, file-rss:0kB, shmem-rss:0kB, UID:0 pgtab0 2811:13.62 error: could not compile gkrust (lib) 2811:14.39 Caused by: 2811:14.50 process didn't exit successfully: `/root/.rustup/toolchains/stable-riscv64gc-unknown-linux-gnu/bin/rustc --crate-name gkrust --e) 2813:03.10 gmake[4]: *** force-cargo-library-build Error 101 2813:03.15 gmake[3]: *** toolkit/library/rust/target-objects Error 2 2813:03.44 gmake[2]: *** compile Error 2 2813:03.70 gmake[1]: *** default Error 2 2813:03.90 gmake: *** [client.mk:60: build] Error 2 2813:04.19 W 271 compiler warnings present.

Could you please help me troubleshoot or suggest how to resolve the memory issue?

Any help & support is greatly appreciated!

Firefox uses too much memory, with 1 tab 1GB+, and with 4 tabs all 3GB+, this is not normal, the forum topic did not help, reinstalled and did not help, there are no more than 6 extensions, and they consume only 160mb.

i noticed that my laptop is getting too hot, when i opened task manger i found that Firefox is using a lot of ressources every time, i have a decent ram of 24GB and i7 7th gen plus an gtx1050, i don't think it's my work flow because i've been always using too much tabs without any problem, i suspect an update issue, what do you think ?

Power consumption of Firefox is so high that it nearly killed the display of my iMac. My screen started flickering with horizontal lines across the display. When i touched the screen, it was so hot that I could boil water using it. I did not realize that it was Firefox that was killing my PC until I looked at the power consumption (see the attached screenshot). I hope there is a solution to this since I really love Firefox and have been using it for well over a decade.
