What minimum memory spec is recommended for current Firefox usage? Have new computer with 16GB memory, 512 storage, intel core Ultra 5-225 processor & windows 11. Have not set it up yet.

Was prompted for various system updates including apps(Firefox). Performance has been very sluggish. At some points, it feels like I'm browsing on dialup. I have a 1GB connection from my ISP.

Not sure if this is a Firefox issue or in conjunction with the other system updates.

For the past few weeks Firefox has been crashing and freezing often. Crashes are worst when trying to access Protonmail, which almost always crashes the tab instantly. Freezes happen most often when browsing Reddit, and also when watching Youtube, but crashes and freezes can happen on almost any website.

I have tried changing profiles, refreshing and uninstalling/reinstalling, but the problem persists and seems to be getting worse over time.

Here are some recent crash reports:

Will be grateful if someone can help me get to the bottom of this Thanks

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.

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.

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.

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?

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...

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

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?

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.

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.
