Firefox has been using more RAM and CPU on my system recently, especially with only a few tabs open. Is this expected behavior, or are there specific settings, extensions, or configurations I should check to improve performance?

Warning Unresponsive script, this popup causes many issues as I use many tabs and it will get the popup and the only choice I have is to say continue, that then redirects me to that tab, so what I was doing gets interrupted. I have to go and find the tab I was working in when I may get another popup. I've had it where I've had popup under other popups, I tried the extending the time but that seemed to make things worse.

I need to totally disable that popup, tell me how.

Firefox I'm getting nothing done, Do I really need to use chrome?

In 2024-25 Microsoft Edge gained the ability to limit the usage of physical RAM that the processes uses. Once that limit is reached tabs are put to sleep or are unloaded. So a user of Microsoft Edge could restrict the memory usage to say 1GB or 2GB or 3GB and so on till the maximum available physical RAM.

Does Firefox have such an ability? Is there some flag or settings in about:config that can be enabled for a similar feature to be used? Does Firefox have ability to put tabs to sleep once SWAP is started to be used? Is there some flag or settings in about:config that can be enabled for a similar feature to be used?

If none of one of the above is not available with Firefox then will Firefox add this feature as part of the browser in the future?

Firefox freezes when I try to sign into YouTube via Google. Becomes totally unresponsive and I have to close browser. It's the only site this happens on. I have cleared the cache and cookies, unchecked "Hardware Acceleration" and other recommendations from other posts. Please talk to me like I'm your Baby Boomer dad.

Anyone else having an issue with the newest firefox in Linux Mint? I don't know what's causing it but when multiple tabs open my address bar and all other primary buttons/icons (including the menu button) don't work, only the download button. Across multiple tabs. Not using any groupings/classifications or any "new" tab features or vertical windows etc.

I use a Mac running macOS Sequoia 15.7.2. Each time I attempt to login to https://music.amazon.com, Firefox freezes which then requires me to quit Firefox and restart. Therefore, I need to use another browser to access the site. What is the solution to this issue?

I have been using Firefox for many, many years. As of late I find it is constantly slowing or freezing and when I check with taskmanager I find Firefox has opened and is running as many as 85 processes. I have tried the recommended methods of limiting it...but the performance options do not provide the ability to limit processes as set out in the instructions....and changing the browser.tabs.remote.autostart to false also did not work. If I can't fix this, I will have to stop using Firefox. I am using version 144.0

I use a Lenovo Legion 5 laptop pc and a second Samsung monitor. When the screens go to sleep with Firefox open on the second monitor, the second screen will not wake up again instantly. It can take up to 5 minutes or only after rebooting.

When I close the Firefox window on the second screen from the taskbar on the laptop, the second screen lights up again.

Any ideas?

Thanks!

Добрый день! Обратил внимание, что с последним обновлением. у меня стала виснуть браузерная строка полностью и я не могу зайти в настройка. Уже было несколько раз так и мне помогает только полный перезапуск браузера.

Я могу прислать видео, как это выглядит.

Прошу помочь решить эту проблему. Спасибо

Using Google Voice became unusable. Firefox too slow. Had been running just fine up till maybe a month ago when I finally gave in and allowed Firefox to update. Not knowing if it was a Windows or other issue I stupidly did a Windows reset and lost all my installed programs (including Firefox). I did a fresh install of Firefox and manually reentered passwords and bookmarks.

Ran fine for a day or two and is now again unusable. Cleared cache and appears to work OK at the moment but still sluggish.

Hi, After updating to the latest version of Firefox on my laptop, I’ve noticed that the battery drains much faster than before. I haven’t changed any settings, but the browser seems to consume more power even with just a few tabs open.

I’ve already tried:

Restarting my laptop

Disabling unnecessary extensions

Clearing cache

But the issue is still there. Is there any specific setting or workaround to reduce battery usage in the new update?

Thanks in advance!

Your browser dead ass just doesn't respond when I click on it. I have a new mac mini 4 and have the latest update for firefox. it's absolute dogshit to be honest. I'm lucky if the browser lets me click on anything, eg., bookmarks, add-ons, history are nonfunctional. Also my tabs on the browser get squished together and superimposed such that 2-3 separate tabs appear as though they are one tab. I have never had an issue like this before when using firefox. I don't encounter the issue with safari or chrome, but I don't like those browsers. Do you have insight as to why firefox mozilla is suddently ass?

I have an issue where my firefox freezes whenever I try to take certain actions inside home assistants music assistant. I have created the following profiler of the issue https://share.firefox.dev/4pPZRPo

I have tried all the recommended settings to mitigate these kinds of problems (remove hardware acceleration, set disable all addons). I don't know where to report this exactly, but I'm hoping someone might be able to see something from the profiler that could illuminate what exactly is going wrong?

Notably this issue does not happen in firefox private mode.

Hello. From time to time, a problem with tabs and the settings button in the Mozilla browser occurs. The tab close buttons and the settings button stop responding, are not pressed, tabs have to be closed manually using the right mouse button. Everything starts working after restarting the browser, but again after some time everything stops working again. This happened on version 138 and I observe it on 139. Installed Operating System: Garuda Linux KDE Plasma Version: 6.3.5 KDE Frameworks Version: 6.14.0 Qt Version: 6.9.0 Kernel Version: 6.14.9-zen1-1-zen (64-bit) Graphics Platform: Wayland

The lack of a title bar makes it impossible, for example, to close the application by pressing the "X" icon in the upper right corner. The title bar does not appear when the application starts, but does appear when the application window is minimized and then maximized.

I have been using Firefox for awhile now and something weird is happening. I can't close tabs by clicking on the 'x' on the tab. I also can't use the back arrow and the refresh button. I can right click and close tabs that way and the bookmark bar works. The problem seems confined to the top two bars. Thank you.
