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.

'I am running fiefox version 147.0.3 in MacOS version 26.2. Every second time I start the program firefox tries to take 15GB of memory. The process does not respond (as this is equivalent to more than the memory available plus the swap space). I have to kill the process and the second time the program has standar memory needs. How can I help developers?

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!

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 around 60 tabs open accross 5 windows, and whenever I try to open a new tab, Firefox takes many minutes to load completely. I've restarted Firefox and the problem is solved for a few days, and then it persists. I've been using Google, but I want to keep using Firefox. Fix it now please.

Sporadically over the past year, a virus warning, purportedly from Apple, has locked my FireFox screen. I must Force Quit to unlock FoxFire. See images. Is this a scam?

When I launch Firefox, it uses well under 1GB in memory, but then it starts to increase that amount quickly in just a few minutes and gets up to 50+GB, causing error messages to pop up repeatedly until it uses all resources and locks up my computer. I have updated my MAC OS and the Firefox app, uninstalled the Firefox App and still have the same problem.

Please help

Version 148 is very slow. When there are 5-10 downloads, other websites won't open. That's why I use version 140. And why are there so many files in the folder - ....profile\storage\permanent\chrome
