On my main desktop computer whenever I try to open a Channel page on YouTube, Firefox will start to lag and either tell me it is slowing down Firefox and I need to stop the tab or just crash.

Sometimes after I refresh a random number of times, it will load the videos tab and then be fine on that channel. On other occasions it will never load the channel's Home page or Videos page and I have to close the tab because it won't load or change.

This only happens on my desktop computer. It it more likely to happen if the page has a home screen video.

Let me know what you think. Thanks

I am running Firefox on Windows 10 64-bit, and I have lots of windows and tabs open. Occasionally I will get a message from Windows that I am running low on disk space. Recently I got the message, and I saw on my C-drive" "336,044,032 bytes free". After I did an Exit in Firefox, I saw "10,082,402,304 bytes free". The space that was freed was in the pagefile.sys file. Is this normal?

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?

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.

For the last day I've been having a problem with FF slow to load. I've tried the troubleshoot mode with little change. When it does load I can have problems with certain web sites loading e.g. Youtube, MSNBC, AOL mail etc. It's never consistent. The cache is clean and I've saved all the relevant cookies, I checked my internet provider and they are having no problems and I don't seem to be having any internal hdw issues e.g. ethernet cable connections etc. I reinstalled FF-not a clean install and seemed to help for a time. Do I have any options other than a refresh? I don't seem to be having the same issues with Edge or Chrome. All W11 updates are current. I look forward to anyone's comments.

a black box appears over the search box when mouse is moved over the tab. Tried in safe and troubleshoot mode. Box still appears only in white I did find an answer previously but reinstalled firefox and the fix was lost. Problem resolved.

Thanks all for looking.

Hello,

This new version of firefox. I am experiencing icons grey out whenever I opened a new tab. Is anyone experiencing this below?

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.

Firefox is using about 15-20% of my CPU, with only one tab open. Running Firefox 141.0.3 (64-bit). I changed performance settings as suggested in support page; made no apparent difference. Ran Malwarebytes and McAfee scans; nothing detected. I have used Firefox for nearly 20 years, but if I cannot resolve this then I will drop Firefox and switch to another browser.

Anyone else see this? When I click the mouse wheel to enable autoscrolling, before I get halfway down the page Firefox starts eating up processor time. You can hear the fan start spinning up until it is screaming at 90%

Mozilla Firefox for Linux Mint Mint-001 - 1.0 142.0 (64-bit)

firefox stalls on ubuntu and the OS says it is running but I cannot or don't know how to restart/reset it from the terminal. A reboot of the computer solves the issue but I have to re enter the bios password etc. Is there a simple solution?

Today Firefox crashed twice and a Tab crashed once! What's going on with Firefox? It's especially disurbing to have it crash during a long video and then you have to find where you left off.

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...

Firefox Nightly (next generation web browser test) has no animation delay when playing sprunki, but there is a bug in the beta and current versions that become delay. (That's why I use other browsers.) There is no delay in other browsers. I hope it will be fixed.

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 had 128.7 esr installed and was getting crashes and upgraded to 128.8 esr and it was worse. Down graded to 128.0 esr and it seems to be working just fine so I will not be doing any further upgrades.
