I-Firefox Community Forum

I love Firefox and have used it forever. But its memory usage is killing me lately and I'm seriously reconsidering.... PC, Win11, Intel7, 16GB memory. (I'm typing this from Chrome)

I've updated, restarted, but it keeps maxing out and slowing my computer to a crawl. Somebody please tell me there's a fix pending?

Gentlemen, isn't your browser using a lot of RAM? I've been freaking out about it in recent years. That's only with 25 tabs open!! Despite the fact that the system was installed just a day ago, without any tweaks!!!

Been using Firefox for over a decade. But lately is has become so slow now. Often freezes up if more than two tabs are open or a website is in any way very complex. What settings and issues should I check? What has changed? I can run the same sites on Brave and Edge browsers with no issues or not nearly as slow and bogged down.

I am facing a recurring issue while browsing websites on Firefox. This happened even before the latest upgrade. Only it is worse after this last software upgrade.

After using the browser for 1–2 minutes, the browser gets stuck or becomes unresponsive. While scrolling through websites, the full page does not load properly, and parts of the webpage suddenly become blank. In many cases, the existing tab cannot even be refreshed. I have to close the program, wait a few minutes and reopen. Very frustrating. I have been using Firefox for many years and this is the most unstable I have ever seen it. Browser Version: [151.0.4(64-bit)] Operating System: [Windows 11]

Looking forward to your support.

Sometimes, for no apparent reason, on my Win 11 ASUS laptop, Firefox will suddenly use a lot of resources, such that the temperature jumps from about 50 degrees to 95 degrees and the fan runs full speed. It appears the only way to stop it, is to close FF then reopen. What might cause that?

I also have an unanswered previous question about being unable to pay accounts.

Cheers, Keith

whenever i scroll trough a website in firefox, the ewperience is very laggy, feels like its 15fps. i have done basic things like disabling hardware acceleration, smooth smooth scrolling.

On Windows 11 laptops, I am currently using an Acer Nitro w/ 12th gen Intel i5 16GB RAM, I use my touch pad for scrolling on sites with infinite scrolling. Occasionally this function breaks, when it does it breaks for every tab in the browser window including the setting, I haven't found a singular or specific cause yet. I have troubleshooted it in the community, the prevailing logic being that themes or extensions are causing some incompatibility, so I have reset everything to defaults and made sure I have no extensions loaded, and the problem persists. I can temporarily fix the issue by going into my settings and turning hardware acceleration on and off again. I am writing this to hopefully point out this bug as clearly as possible in hopes that your programmers can fix it in a future update, as repeatedly turning a setting on and off to "fix" it might not be the best solution in the long term.

This problem is persistent and problematic.

my machine is frequently freezingfor windows 11. At first installation is done it is very super and runs the videos which i liked. now it is very slow and video strucking

I open Firefox, my browser, then I type in the site I want to open. It opens fine, however, when I try to open another site I want to open nothing happens except a little dot in front of the requested site keeps going back and forth, but nothing opens. I then have to close the browser, re-open the browser and key in the site I want. WHY? What am I doing wrong. Please keep in mind that I am not a computer savvy person and don't understand much about them. I do know however that Firefox used to work on my computer before update 150 and 151 were downloaded without a hitch. I have tried everything I could think of to fix the problem without success. I am beyond frustrated and need this fixed.

Having heard the news that Firefox's latest CEO wants to turn it into yet another AI-slop browser, I came to this forum to give feedback as an avid Firefox user over the last 4-5 years. I can see I'm not alone either; there are tons of other users who seem to feel the same way I do.

This is a very, VERY bad decision. So far, every "AI update" that has already hit Firefox has done nothing but make the browser worse and more inefficient. A few months ago, Mozilla was getting hit by complaints from desktop users about memory usage skyrocketing due to the implementation of an AI chatbot into Firefox. Now they've added AI search engines among other things. And surprise, surprise--no one seems to actually want to use these features. Why should we, if all it does is make computers run slower, overheat, and doesn't actually answer any useful questions or contribute anything meaningful?

I'm baffled at Mr. Enzor-DeMeo saying he wants to go all-in on making Firefox an "AI browser" with his whole chest in the SAME week that Microsoft has had to lower their growth targets for AI-related sales, some of them up to 50%, because NO ONE seems to actually be buying AI products. You know, on account of (you guessed it) not finding them very useful.

Other people have already mentioned the myriad of other problems with AI too, so I won't touch on those too much, other than to agree that AI is a plagiarism machine that's doing serious environmental damage. What I WILL say is that I personally have been using Firefox all this time specifically because it's avoided the AI craze as much as other browsers, or at the very least, avoided making it "opt-out" instead of "opt-in" to the same degree. But if this changes in the near future and Firefox does become yet another inefficient AI slopfest of a browser, I may seriously rethink my loyalty to Firefox and switch back to Chrome instead. After all, there would be functionally no difference between the two browsers anyway!

Please rethink this decision and consider actually listening to user feedback going forward. If Mozilla actually wants to retain their userbase, I'm sure I'm not the only person thinking about dropping Firefox for Chrome in the future.

I have been dealing with an issue in Firefox on Windows 11 for several weeks now hoping for a fix soon but it has not come yet. When I am browsing on eBay, it will lock up and I have to identify the thread in Task Manger and kill it (just the runaway thread, not the entire program). I can then continue of eBay for a short time before it happens again. This only happens on eBay while just browsing, not bidding/buying. Is anyone else having this issue?

For some reason, the Menu Bar kept coming up, even after I disabled it. I tired a few about:config things, the one that seemed to work was to disable the ALT key. But I still can't click anything in a game with my mouse while firefox is open. I have two monitors. I have uninstalled and reinstalled Firefox. I've looked around the internet and I can't seem to find my exact problem. Please, please help!

On a random basis, sites like msn.com, yahoo mail or outlook.com will freeze. Sometimes they may suddenly come back to life, but the normal fix is delete tab and restart tab. Long videos may also freeze. Have cleared history, and changed optimization setting but nothing helps. On 151.0.2 64 bit.

Every couple of minutes Firefox just freezes. YouTube buffers, all open tabs just stop working. I can open new tabs but i cannot search up anything or go into any websites. Is there any fix for this?
