AMD ReLive instant replay does not work if mozilla firefox is open in the background while playing a game. It works fine with Google Chrome running in the background, closing firefox "fixes" the issue.

I use a MacBook Air running on Sequoia 15.5. Firefox was updated several days ago to 140.0.2 (aarch64).

Since yesterday, Firefox has repeatedly stopped running. (It might have started sooner, but I didn't use the computer over the long weekend.) It won't load pages. Sometimes I get the spinning wheel. Usually, I have to force quit.

I've cleared the cache, restarted the browser, and restarted the computer repeatedly. Restarting the computer sometimes helps. Now is not one of those times.

Also, the About Firefox window is open, and the Checking for updates . . . wheel keeps spinning.

There are no connectivity issues otherwise with my computer or other apps.

Does anyone know why this is happening? Do I need to go back to the last version of Firefox? Uninstall/reinstall?

When navigating through video websites, the browser often becomes unresponsive and refreshes the interface. When accessing other websites, the browser tabs frequently experience crashes.

Details regarding the operating system, laptop model, and browser version are provided below, and the screenshot of unresponsive website has been attached with this, um email or message.

Hi, Once last week I had Firefox crash, like quite literally the window I had open just closed abruptly. Tried doing the refresh using the setup wizard and it did not help. Then I've tried uninstalling/reinstalling several times. Each time it'll open up like new, and within 10 minutes the window closes randomly and then Firefox doesn't launch anymore on my laptop. No error message, just does not launch whether I try to from taskbar or Home or even run as administrator. Seemingly random I've been using Firefox for months and it just started doing this last week.

Sorry for lack of other info, thanks for any help you're able to give.

Когда firefox зависает и windows предлагает его убить, firefox получает права системы и по этому становиться не убиваемым.Система не может его убить потому что у его права системы .В первые заметил этот баг когда сделал браузер firefox браузером по умолчанию.У меня сим роутер при запуске системы открывает браузер тут та браузер и зависает (не всегда ,но часто) в диспетчере задач в этот момент у его права системы.Писал в майрософт ,майкрософт посоветовал пользоваться нормальным браузером и сменить браузер по умолчанию .По совету майкрософт сменил браузер по умолчанию на chrome проблема пропала. Firefox 140.0.2 (64-разрядный) Windows 11 версия 24H2

Every 1 - 2 hours Firefox stops loading pages and I have to shut it down and restart it and restarting takes around 6 clicks on the icon to get it to start.

Also one time today I lost all my pinned tabs and had to manually restore them one at a time.

Using Ubuntu 24.04.2 and latest Firefox. Cleared cache but doesn't help.

What can I do about excessive memory usage by Firefox? I'm about ready to remove from my system. I get memory availability alerts from my very up to date Mac system only when Firefox is active. I've been with you for a LONG time so hate to leave but this is not a good situation.

This is a technical question. Recently, Mozilla added the ability to manually restart the GPU process in about:processes, which is very useful when it leaks memory. Does anyone know if they also programmed Firefox to automatically restart the GPU process if its memory usage becomes suspiciously high, for example, if it exceeds a very high percentage of system RAM at a reasonable baseline (e.g. 7GB out of 8GB RAM)? That would help reduce complaints about GPU process memory leaks. Thanks.

Firefox has stopped working about 5 times in the last few days while browsing? sometimes on Youtube sometimes it just completely freezes and wont even close with task manager I had to force my pc to reboot yetserday because it wouldnt respond, my pc is rock solid stable while doing anything else including gaming and is 16 months old and have never crashed even once???

Why after the most recent update to version 139.0.4 64bit does any Google search result page on Firefox now use 110% cpu according to about:processes? This isn't the first time a Firefox update has caused this to happen on my computer either. It causes extreme system lag until I'm able to close the Google search result page in Firefox, then everything returns to operating normally. In the past subsequent Firefox updates have resolved the issue but it can sometimes be a while before the next update is released and that one is not always the one that fixes it. Is there something I can do resolve this without having to wait for future updates to be released?

Hi Team,

I’ve successfully built Firefox v135 from source on our internal development RISC-V64 platform running on Ubuntu 22.04 with GNOME 42.9 (Xorg & Wayland), Our RISC-V Development platform does include a GPU HW which support HW Acceleration for GNOME & other 3rd Apps (Supporting X & Wayland), and Work seamlessly without any issues.

The FireFox v135 Application (via ./mach run) starts up normally. But the major issue I'm observing is that Firefox browser is very slow and laggy, especially during search operations and video playback on YouTube I see a poor performance. Upon further check I found that the most of the work is getting done over the CPU and the utilization is quite high, which is causing the FireFox to perform poorly. I also did try to switching to "Use hardware acceleration when available" in the Mozilla FireFox Settings, but still there is no difference with or without this check and Mozilla FireFox browsing Experience is very poor.

Kindly do let me know how we can enhance and improve the overall performance of FireFox Browsing Experience on my RISC-V platform. Any Support and Help is highly appreciative!

Attached a Build Steps and Configuration used for building Mozilla FireFox v135 on my RISC-V64 platform, let us know if there is anything missed. Thank you!

**BUILD STEPS**

Hello!

I would be very grateful if you could help me figure it out, the browser suddenly stopped working, does not open any tabs, just a blank screen, does not open settings, some buttons simply do not respond at all. I cleaned the SScleaner yesterday, but I did not select anything special there, it was a basic regular cleaning that the program offers.

How do I fix this? reinstalling does not help, the browser still does not work

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!

A few weeks ago, just after I tried to delete the cache and tracking cookies from Firefox (using AVG TuneUp, which seems to have taken more than I asked it to remove), my browser started refusing to load any new sites, or reload inactive tabs, once I had been using it for about five minutes after rebooting it. It also crashes completely when I try to download or upload anything after that point, which is irritating but does mean I have some crash reports to share (bp-5a7c5f6e-0d55-451a-8b2b-15b360250524 is the latest one). I've tried everything I can think of or find on the Internet - Troubleshoot mode, disabling and re-enabling hardware acceleration, refreshing the browser, uninstalling and re-installing it with and without restarting the computer in-between (which seemed to work for a while), culling tabs (although, if I'm reading the crash reports correctly, lack of memory isn't the issue after all; certainly, Chrome doesn't have the same problem even when using more memory than Firefox did), even running diagnostics on my computer's RAM and hard drive - but nothing's fixed it. What might be going on, and how can I solve this problem?

Firefox has recently started crashing multiple times per day. The crashes do not seem to be website specific.

Here is a list of my submitted crash reports. Please help.
