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.

Hello,

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

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 have been using firefox for 3 to 4 years now and it's the best brower i have ever used but from a few months it have gotten too slow i am a student and need to create projects and research alot so i have to open around 20 tabs at a single time but before even after opening 30 tabs it would be fast as ever. I don't have any security extension or whatever i just have AdGuard AdBlocker extention, volume booster and grammerly and screenshot taker and hoxx vpn (it was before as well) but the firfox has become so slow now. (I have custom and max protection on) and additional windows protection too. and sometimes it just stop responding and also hangs up and closes own it own.

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%

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 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.

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.

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?

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.

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.

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 144.0 on a W11 PC with all updates.

Firefox is running multiple (10-13) windows with 5-10 tabs each. Even if all Firefox windows are minimised and not being used, memory usage goes up all the time. It is currently, according to Task Manager, using over 5 GB of 32 GB of available memory. CPU is sitting at ~4%. Individual tabs, like Youtube watching CNN suddenly freeze and are no langer accessible and can't be unfrozen by anything I have tried. Even the mouse pointer is not displayed inside this tab I need to restart the entire PC several times a day only to have Firefox usable. I have turned off efficiency mode, but this did not change anything. I'll include a system snapshot with msinfo

Any ideas?

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.

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.
