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.

Even with just 1 tab open, Firefox is killing my laptop battery.

Win 11 PC laptop.

In background, it is using 40% to 50% of the laptop battery. I need much better performance from it. I have already turned off any settings I can find regarding Firefox's background functions. When I quit Firefox I want it completely off.

How can I do that?

Hi I always use Firefox on my Apple I-Mac and it has always been excellent but in the last couple of weeks a window pops up to say that Dashlane is slowing down Firefox when I am trying to type in E-Bay. Not yet seen it in any other situation but it it virtually preventing me listing items for sale on E-Bay. Always have Dashlane open on Firefox whenever I am using Firefox/the internet. Today I reinstalled Firefox but it is still doing it. Help please! Kind regards Jeff Worth

For those of us that do want to use AI for work performance enhancement purposes, I have a question and also a comment for the Development Team. Here is the scenario real quick. I use Mozilla Firefox as my trusted browser today and that means that I open other AI systems such as ChatGPT, Grok, Gemini, etc. within this browser and could at times be running multiple browser sessions at the same time. My question is, will the Mozilla new AI Features attempt to try and compete with my other chat sessions for data capture, response and participation if I keep portions or the whole system enabled? The last thing I need is Mozilla AI as the selected browser now interfering with my other work flow processes in anyway including just listening along which would significantly increase the amount of resources used to run the Mozilla AI in parallel with other AI systems on my computer. I have heavy work loads at times and am already experiencing browser delays in processing data (even when setting up separate project chats for specific tasks) because of too many added features within all of the AI systems like historical chat session quick links on the right side of the screen. That's a ton of data that ends up getting stored/cached, referenced and processed with each command executed. I don't mind using Mozilla AI within the browser for general personal surfing and Q&A purposes but I can see this potentially becoming a big issue for us creators working with large image data processing tasks in other AI systems via the Mozilla browser. I will unfortunately be turning all of these Mozilla AI features off to start because I am not sure there really is a clear separation path for resource allocations within the browser now keeping my experience fast and efficient. Most likely this will force me into using a different browser product for personal vs business until things are much clearer. Hoping to learn a little bit here and see that things like this are being taken into consideration, even if it is a product roadmap enhancement for release sometime in the near future. Thanks so much!

opening firefox why is it blank page. When I open up FireFox the page is Blanck the account tab top right dosent work nothing works no search just blank page why is that. Yesterday it was fine worked

OS: Linux Recently, firefox has been annoying me with not closing a tab when I click the X like normal. I have to right click and close it, or press ctrl w. I am unable to move tabs around, as well. I am not sure since when this next bit has been happening, but I am also unable to interact with many elements of the top bar. The only thing of the firefox ui besides the websites themselves that let me interact with them at the moment is the home button, the new tab button, bookmarked sites, and that box icon on the left corner that lets you look at previously closed tabs. My Firefox's version should around, I believe it is 140.5.0 ESR. Thank you in advance. Update: Upon a restart of firefox, it appears to be working again as normal.. However, the bit with tabs not closing when the X is clicked and not being able to move tabs around has been happening multiple previous times, and it may come back. Update again: The issue does come back after some usage. I'm using KDE plasma with Wayland. I will try what the answer asked, and come back later. Update: This seems to happen very randomly and is not reproducible for me.. It will go a few days being fine, then randomly freeze again. Has not happened under another user, at least not yet.

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!

Why does Firefox's hardware usage, especially memory (RAM) and battery consumption, have to be so high that the laptop fan noise causes a lot of noise in the environment? Windows 11 25H2

Windows updates from Oct 14 have messed up both firefox and an extension (Ironvest). Can't access mozilla account from icon on toolbar (just a revolving blue buffering circle), nor will the extension work. Have uninstalled extension, turned off/on computer, reinstalled, no luck. Discovered the mozilla account won't work after this, so resigned in a couple times, still the same issue. Even uninstalled one of the window updates (performance, not security) and still not luck. I hate windows when they update and upset all my settings.

warum ist die obere zeile mit dem kreuz beim start nicht mehr da? Sieh die markierung im Bild! immer wenn ich firefox starte mus ich es erst nochmal minimieren und dann wieder öffnen. was soll der scheiss

und Könntet ihr eure hilfe auch mal auf deutsch machen dann könnte mann wenigstens was lesen ode alles extra übersetzen zu müssen

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.

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

I have removed many gb of apps to try and address this issue today but can't stop Firefox from using an insane amount of memory. What's up? I've been using Firefox for years and have never had this issue until today. I'd like to keep using your browser but I can't if my computer keeps shutting down.
