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.

It keeps happening randomly and I have no idea why!

I've attached a screen grab so you can see what I mean.

When this happens I have to close down the tabs in question and then reopen them.

Never had this issue before.

Performance Issue Report: Firefox Unresponsive with High Memory Usage on macOS

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 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!

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’ve noticed that Firefox often uses a lot of memory when I have multiple tabs open, even more than Chrome or Edge on the same number of tabs. Sometimes it slows down my system or makes switching between tabs laggy.

Is this normal behavior, or is there a way to reduce Firefox’s RAM usage without losing performance? Are there specific settings, add-ons, or troubleshooting steps I should try?

Thanks in advance!
