Lately, I’ve noticed Firefox consuming more RAM, especially with multiple tabs open. Is this a common issue in recent updates? What are some tips to optimize Firefox performance on lower-end PCs? Would love to hear your experiences!

Will this fricking "The bookmarks and history system will not be functional" B.S. ever be fixed? Firefox didn't have this issue for years now for almost a year every time Firefox starts up on a cold boot I get this idiotic non-sense message!. I have to close the browser I JUST OPENED and reopen in. This error is pure B.S. as again cold boot, just launched there is NOTHING other than Firefox that might be accessing the various sql.db's...so if this message is to be believed Firefox is blocking Firefox from Firefox... FIX THIS!

When I open Firefox it opens a maximized window with tabs, then it opens a minimized with a single tab, then it reopens a maximized window with all session tabs. Each window displays in succession, one window at a time.

I'm on desktop using Windows 11.

I just read a post saying this behavior was caused by the resist fingerprinting feature. Can someone explain how that causes the repeated opening of browser window 3 times. Is there a way to retain the anti-fingerprinting behavior w/o the multiple window opening behavior?

I AM SENDING TWO SCREENSHOTS IN ORDER FOR YOU TO SEE WHY I AM SAYING GOOD BYE TO FIREFOX OVER 4000 OF RESOURCES AS YOU CAN SEE AND FIREFOX HAD 4 TABS OPEN ALL OF THEN JUST OPENED UP SO THEY WERE NOT YET CONNECTED TO ANY WEBPAGE.

I CANNOT SPEND HOURS TRYING TO FIX THIS

SO I AM MOVING TO ANOTHER BROWSER

I JUST WANTED TO SAY CIAO

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.

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.

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

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)

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.

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?
