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.

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!

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.

When i start fire fox it immediately opens 10 additional versions in the background which I can see in task manager and they take up a lot off memory. If i end task them they immediately come back. This only started recently. I noticed it because now when i open say a youtube video it shows it as number 4. This never happened before unless I had the same video open more than once.

If I can not stop this I will have to uninstall.

after working in firefox for a while and using a number of windows and the I close firefox with multiple windows open in my session. if i open it again and keep doing this for a while and then have closed firefox, eventually I can no longer open a firefox window and get a message the I have too many windows opn and can't open more till i close the open windows. i hover over the firefox app and all the previously closed windows are stacked up. why didn;t they close when i exited my firefox sessions. why are they still there and clogging up the system?

Two questions; First is why does the Taskbar show "Firefox (2)" (see first image) Second: When trying to troubleshoot, I open Task Manager, and with just one tab open, I see Firefox (13); confirmed when the line is expanded. What is going on here and is it impacting Firefox performance; see 2d and 3d images? (Phone camera photos as PrintScreen is disabled for Task Manager which doesn't seem smart)

I am on a new PC with Windows 11, using 4 monitors. I keep trying to figure out what is making my mouse and sometimes the keyboard behave sluggish (freezes for a moment). I have takes all suggestions that AI has suggested but it is still happening. Do you have any thing for me to try? It appears to be only when Firefox is running.

For the last couple of days, the Firefox instance goes black and the title bar turns to an old windows look (see picture). Or turns fully blue, the color of browser theme, and the title bar is covered as well. There is no certain page that makes this bug appear, it appears randomly regardless of the page I'm visiting. Often it happens on the Firefox instance that is on the monitor I'm not working on at that moment. For example, I am browsing on my main monitor, and the 2nd monitor has a page open, the page in the 2nd monitor becomes bugged. It happens the other way too. Current Firefox version is 149.0 64 bit version, but i think it happened before the update too. I have already tried to turn hardware acceleration on and off again.

在 Firefox 内部：

通过 JS 触发的新页面 通过 a.click 触发的新页面 甚至 rel=noopener 都会被标记为：

“related browsing context”

进而共享同一个进程，新页签因为内存占用过高，导致旧页签卡死。

通过设置

1. 添加 COOP 响应头 add_header Cross-Origin-Opener-Policy "same-origin" always;也无法解决

设置空白页再重定向也无法解决
