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.

Subject: Assistance Required for Frequent Firefox Crashes on Ubuntu

Dear Developer Team,

I am facing persistent issues with Firefox crashing on my Ubuntu PC, and the problem has been ongoing for the past 40–50 days. Despite multiple attempts at troubleshooting—including uninstalling and reinstalling Firefox, clearing all caches, and other measures—the issue remains unresolved.

I’ve noticed that Firefox works for a few days after reinstallation, but then problems begin to surface, such as a half-screen display. Eventually, after restarting the PC, the browser starts crashing again.

Could you please investigate this matter urgently and provide a resolution? Additionally, I would appreciate it if you could clarify whether this might be related to a RAM issue or some other underlying cause.

Looking forward to your assistance.

Best regards, zimmi

I have observed that firefox has a coloring problem. When firefox is minimized to the toolbar, after a while, maybe a few minutes, when it is opened, there is always black uncolored content at the bottom of the screen, occupying about 1/3 of the height.

Attached are two screenshots.

My computer, being 7 years old (and without the space to upgrade to WIN11), has always been a bit slow with low RAM and storage. The swap from Chrome to Firefox essentially gave it a second life, as Firefox didn't need a lot of space to run. Recently, though, it locks up with almost every search, refusing to let me x out a tab and try to save myself for 3 minutes or more, and the bluescreens have come back, too. If chrome hasn't also gotten worse, I'm considering switching back. Does anyone know what happened? I haven't installed anything new.

It's really frustrating and disappointing, because I thought I had a solution when I swapped to Firefox.

Hello !

I recently got a new laptop (Lenovo Legion 5 I think) and while it's been working great, I've noticed a glitch that's happened a few times now. It's usually preceded by the image having some weird line pattern, I haven't been able to take a picture of it but it's almost like the pixels have been shifted ever so slightly. After that the screen sometimes splits strangely (see image). I don't know if this is a hardware problem or a Firefox thing but the only time it has happened was when I was on Firefox so yeah...

when I start firefox, it tells me the old one is running and to close it. i hit the close button and keep getting the same message. I have uninstalled firefox and reinstalled it and keep getting the same problem.

I tried all common troubleshooting steps: deleting cache reinstalling different settings turning off adblocker/vpn disabled efficiency in task manager and set it permanently to off in FF

I used to have 1000+ tabs in 2016 no issue. I had problem in past with Firefox using 100% CPU which now it is not using only like 50, but memory is getting full 89% i use also large page file on ssd. Problem is even when i restart firefox it is slow with low RAM usage! SO that's not it! Even 5 tabs sometimes it is slow!

It is so damn slow it drives me crazy! I tried also Quantum in past when Firefox has 100% CPU usage bug and it was only tiny bit better but still caused 100% CPU usage!

All other browsers are anti user cannot even stop Autoplay literal terrorist Firefox is only normal browser unfortunately performance compare to 2016 got absolutely abysmal! I had this problem even in-between reinstals of OS so it doesn't seem it is me. I play demanding games no issues on my PC...

Hello,

Hopefully this is something that can get answered quickly. These past few days I have not been able to use FireFox on my laptop.

It doesn't seem to be a wifi connection issue because other browsers work and other devices are connected just fine.

I also tried opening FireFox in the "troubleshoot" mode, but I am still receiving the same errors. I would appreciate any help I can get on this issue.

Below is a screenshot of the error I keep receiving.

Thanks,

So, i have a laptop, with integrated cpu graphics (Intel UHD) and discrete gpu (RTX 3060), first times when i set in Windows settings to use Firefox powerful gpu, it just won't, i tried restarting browser but i forgot that i have opened private tab, so i not restarted browser. So, on any pages like WebGL Aquarium, i have pretty low fps, in comparison to other browsers (like Microsoft Edge or Google Chrome). Then, after i see that tab, i closed it, and after restart i got my fps, but.. still lower than other browsers, on WebGL Aquarium with 30k fishes, Firefox max fps is around 35, but on Chrome is around 70 (two times faster). I found one page that shows gpu that uses for acceleration, and it shows pretty weird information in Firefox. https://kdashg.github.io/misc/webgl/low-power.html So, in Chrome it says like "Nvidia RTX 3060 Mobile GPU", and when i choose integrated gpu for this browser in windows, it says like "Intel UHD GPU", but, in Firefox, on first tries it said same, but when i got discrete gpu acceleration, it says that i have "Nvidia Geforce GTX 980". I was like, what? Where it did come from? This explains why I have a fps two times lower but who will explain to me why this gpu is here? I tried to change all acceleration settings in browser, but when i just disabled any acceleration, still shows GTX 980 what is more weird than if it just shows like nothing or Intel GPU, cause is disabled but still uses hardware acceleration, but no matters if i let Firefox use recommended performance settings or set to use acceleration when is available, it shows GTX 980. I think it's about a bug, or something? I can't say that's Windows problems, drivers, or any other thing, cause, other browsers don't act like this, and i just don't have GTX 980 in my laptop on side with RTX 3060 and Intel GPU, anyone even know that laptop like this exists? Screenshot don't wanna upload here so i decided to place it on imgur. https://imgur.com/pyMZQr0

From the last two Firefox updates, I no longer can move sites screens around on my Mac Air laptop. Only one page at a time shows up and consumes the screen. I am no longer able to copy and past and move info to another screen. A couple of weeks agom I cleared my cache but not sure that had anything to do with it. Please suggest solutions. Is there an add on or something that needs adjusting?

Thank you.

Despite being listed as supported on: https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/enumerateDevices

enumerateDevices() still only returns input devices. Running navigator.mediaDevices.enumerateDevices().then(devices => console.log(devices)); in the Firefox console only shows input devices while on Chrome it shows output devices.

I use a website that supports playing from multiple output devices so when receiving a phone call, your desktop speakers and your headset can ring at the same time. This works in Chrome but it doesn't in Firefox.

Hi Team,

When we enable Netskope, all the searches breaks (specifically with Google Search Engine). It takes about 2 to 3 mins to do the first search, after which it continues to work normally.

Furthermore, facebook takes too long to load (~4mins).

The netskope support team has asked us to make a few changes in about:config: 1. network.http.http3.enabled 2. QUIC protocol 3. network.udp.enabled

None of this works and even if it works, the problem is we have about 1500 devices.

Are there any reported issues ? And is there anything that we are missing ?

I am trying to access iDRAC 7 on a Dell Poweredge R520. On version 133.0.3 I get a An error occurred during a connection to 192.168.1.20. PR_END_OF_FILE_ERROR. I know that the problem is that Firefox stop supporting older versions of TLS. So I choose to also install an older version of Firefox (43.0). On that version I get a The page you are trying to view cannot be shown because the authenticity of the received data could not be verified error. I used to have no problems accessing iDRAC 7. Has anyone else been able to resolve this problem?

After a few minutes of usage, firefox keeps freezing and crashing. Very frustrating. Seems to have started happening after recent OS upgrade.
