Hello everyone,

I've recently noticed that Firefox has become slower than usual. Some websites take a long time to load, and occasionally the browser feels unresponsive even though my internet connection seems to be working fine. I've already tried restarting Firefox and clearing the cache, but the issue still occurs.

Has anyone experienced something similar or found a solution that improved Firefox's performance? Any suggestions would be appreciated.

Thank you!

Hi,

I am using macbook pro latest one, and when I use firefox and scroll down from my wireless Mouse to the bottom of the page, the scroll bar jumps to the top while working, is there a fix for this.

Thanks

please help me make my computer run better,i have epb fiber optics and its slow and im sure my programs and everything is configured wrong

Hello, I'm on Firefox Nightly 152.0a1 running on a freshly installed new Windows 11 version. I've used Firefox exclusively for my whole life and everything has always been smooth until a few days ago. Firefox started (and continues) to freeze for a second or two pretty regularly, each time I use the search bar for example, open a new tab, while a page is loading (which is very slow at the moment) but also scrolling on a page for example. During the freezes, the temperature of my CPU also increase by approximately 20°C. CPU usage in task manager shows that it is quite high, 10x higher than Edge that I opened for comparison only : https://i.imgur.com/enuMMZl.png.

I have sought the internet for advice but nothing changed this behaviour. I updated my computer through Windows Update, my drivers through Driver Booster, I disabled hardware acceleration on Firefox, I removes all AI components with zoicware/RemoveWindowsAI on GitHub, I changed dom.ipc.processPriorityManager.backgroundUsesEcoQoS on about:config to false but nothing cured the problems.

I'm out of solutions and I don't know if I should be waiting for another Nightly build (usually there's about 1-2 a day but 152.0a1 is sticking since a few days and there isn't any update available since, seemingly), if there's others energy economy parameters I could play with on Windows 11 that I don't know about or if something else is in the way. Any help very appreciated, thanks!

Hi whenever I use my Google account to sign into websites (Google, ebay, YouTube, & anyother sites,) Firefox will become unresponsive, the window containing the tab i was using becomes unresponsive, sort of. - I can't click any open Firefox Tabs, - the red 'Close' radio button is greyed-out, so I can't close any tabs or the window - right-click is unresponsive, so i can't close tabs that way, but Command-W closes the tabs normally, but the others are still unresponsive.

- i can open a new Firefox window (with &/or without Tabs,) which works normally.

- & unrelated, but earlier, Firefox was running really slowly, Youtube videos were slowed down, but audio was normal, and scrolling was slow.

Whenever I have to restart my cpu, the menu bar appears to try to open all of the tabs and it causes system hangups and says that Mozilla Firefox is not responding. What causes this ??

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

Firefoxa używam od lat ale ostatnio strasznie mnie wkur....bo kilka aktualizacji zepsuło ten program, co aktualizacja to gorzej z wyszukiwaniem i pobieraniem np. zdjęć, nie raz nie da się odświeżyć strony, nawet wyczyszczenie historii nie pozwala na nowo wczytać strony zapisanie kolejnego zdjęcia o tej samej nazwie nie pozwala wpisać np; image 1, 2, 3 itp wklejając np: image okno jest nie aktywne by wpisać 1,2, 3, itp; trzeba czekać aż Firefox się namyśli i pozwoli dokończyć wpisywanie, szlag trafia człowieka przy takim działaniu. te wasze aktualizacje gdyby rozwiązywały problemy nie byłoby tyle poprawek Np 150.01, 150.02, 150.03 myślę, że następna aktualizacja 151 będzie bez błędów i wyeliminuje obecne bo inaczej będę musiał zmienić przeglądarkę. I jeszcze jedno wyszukując zdjęcia są one zamazywane i wielokrotnie pojawia się informacja że zmieniliście mi ustawienia przeglądarki (włączony filtr) wyłączam go ale nie ma opcji zapisania ustawień i za jakiś czas sytuacja się powtarza, zróbcie coś z tym i nie decydujcie za mnie co mam włączone a co nie. Tak samo jest z motywami niektórych nie da się usunąć a zaśmiecają kompa. Jurek

Windows 10 Open Firefox (151.0.2) Google "does alton towers still run in the rain"

My CPU then goes to 100% continuously. Why, CPU occupancy has only gone up in the last few weeks. This happens in a lot of searches.

fonts.googleapis.com is locking up websites for 40 to 60 seconds per keystroke. I have researched this problem and tried everything suggested, but nothing works. Much of the solutions include changing the settings used on menus which no longer exist. accounts.google.com is doing the same thing. This is driving me nuts. Help!!! Latest version of Firefox. Windows 11 desktop computer.

After updating to Firefox 138 on Windows 11, startup takes about 30 seconds. Safe Mode is faster. I tried refreshing and it did not help. Marked **bold test** and [a link](https://example.org) plus {{7*7}} literal check.

I've been testing a browser-based metronome in Firefox and noticed that the audio click can sometimes feel slightly out of sync with the visual beat. It isn't a complete audio failure—the metronome keeps running and produces sound—but the timing can feel a little delayed or inconsistent, especially when using it at faster BPMs. The site I'm testing with is TheTapTempo's online metronome. I'm trying to figure out whether this is related to Firefox's handling of web audio or whether the delay is more likely to come from the system/audio device. A few things I'm wondering about: • Could Firefox's Web Audio timing cause a small difference between the scheduled beat and when the sound is actually heard? • Could Bluetooth headphones make the problem more noticeable because of their audio latency? • Can Firefox extensions or hardware acceleration affect the timing of browser-based audio? • Is there a Firefox setting or diagnostic mode that would be useful for testing this? • Would comparing the same metronome in Firefox and another browser help determine whether the issue is Firefox-specific? I've also noticed that the perceived timing can depend on the audio output being used, so I'm not sure whether this should be treated as a Firefox issue or an audio-device latency issue. What's the best way to troubleshoot this in Firefox?

For at least a few months now, my browser will suddenly and randomly go fullscreen all by itself. I can't exit it, and then it goes back to normal after at most a minute. It hasn't happened in at least a week. But today, it froze like that, not responding. I quit firefox, waited a bit, then restarted it. It went fullscreen and froze again. I waited at least 10min and it then went back to normal and responded again. It only happens when using firefox. I've done virus scans, etc, and it still keeps happening. Please help. Thanks.

A week ago, Firefox started freezing and acting all glitchy. Troubleshooting said to uninstall and reinstall, which I did. That's when the real trouble began. It lost all my data, pretty much signed me on as a brand-new user. Luckily, I was able to recover my data from my phone app, but it still did not work correctly. Nothing in the support pages was helpful, so I finally had ChatGPT assist. We got it restored using my recovery key and I though that everything was fixed. Then two days ago I got the 'not responding' thing happening every time I tried to reopen it, along with a generic Firefox web page opening randomly. I reopened it several times in troubleshooting mode, again, no help. So. uninstall, reinstall, uninstall, reinstall... you get the picture. I finally thought I had gotten it properly restored at 5:30 this morning with all my previous tabs showing up. But as soon as I tried to use it, the same old 'not responding' message. I always get the pop-up asking me if I want to close it or wait for it to respond, which it will eventually do, until I try to click on a tab. What the hell am I missing here? I've had Firefox for, oh, I don't know, 20 years or so. Never had problems.

This has been in the last month or so. It will freeze up and I can't break out of it. Last time it froze the whole computer and I had to power down and restart. There must be something that changed. And there must be some way for me to be able to quit when this happens. Last time it was on a video call with my 104 year old mother and it is very annoying. The whole thing froze and I had to restart the computer and when I got it back up, she was off. I need some way to break out so I don't have to do a complete restart. t.
