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.

The minimize, maximize, close line at the top of the screen is missing when Firefox opens. If I click the Firefox icon in the task manager to minimize it and click it again to maximize it, then the missing line at the top appears. This has been an ongoing glitch for a week or more. Perhaps you can fix this minor problem?

Dear Firefox Support Team,

I am writing to report an issue I’ve been experiencing with Firefox on my MacBook Air (M3, 8GB RAM). Recently, Firefox has been becoming unresponsive quite often, and the Activity Monitor shows significantly high memory usage. For context, I typically have two Firefox windows running simultaneously, with approximately 5 tabs open in each window (10 tabs total). This is when I notice the performance degradation and high memory usage.

To help you investigate, I’ve attached:

• A screenshot of the memory usage in Activity Monitor when Firefox is running.
• A screenshot of the extensions currently enabled in Firefox.

I am open to suggestions, such as disabling or removing certain extensions if they might be causing conflicts. However, I wanted to report this issue first to understand if this is a known problem or if there are optimizations planned for Firefox on Apple Silicon Macs.

Let me know if you need additional details, such as Firefox version, macOS version, or specific steps to reproduce the issue. I’d be happy to provide any information that can help resolve this.

Thank you for your time and assistance. I look forward to your response.

Best regards, Hemant

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.

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

This is happening more frequently. sometimes clicking links works but the cursor will not respond if i hover over the new tab button. To continue I have to select a new firefox window, The unresponsive window remains in error even when a new working window is active.

just takes to long to start, when i turn the computer on. Google Or Microsoft will come on almost instantly & when Firefox comes on, it says turn it off cause its running but not responding. this happens 80 to 90 % of the time. Why ?

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.

What causes Firefox to freeze when two video windows are opened, i.e. in a new tab, the video windows immediately start to freeze? I use Windows 11. Other browsers work fine, only Firefox freezes with two windows open.
