Firefox Community Forum

Hi, I use Firefox all the time, love it. But I have noticed a problem.

If I have say 7 tabs open, none of them doing anything, then go away from my laptop for say 20 minutes, when I come back the fans on the laptop are screaming. Even if it was minimise.

I have a fairly modern laptop Dell GSeries1522, 12th gen processor, 16gb ram, i7.

I have tested this issue using Edge and Chrome with exactly the same tabs open and the laptop is all quiet. I'm on the precipice of moving to Edge. Happy to provide more information. Task Manager now shows FF using 1223.0mb of memory, Edge 466.7mb. They are both in "efficiency mode".

Any help or advice would be great.

I already have "Automatically install updates" and "When Firefox is not running" enabled.

But after each Firefox update I still get the "Do you want to allow this app to make changes..." prompt and "Firefox is installing your updates and will start in a few moments" window. These are inconvenient as they require user input and take up time.

I don't get these on all other browsers I use (including Chrome, Edge, Safari, Firefox, Opera, Vivaldi, Brave), which all update in the background seamlessly.

Is there a way to prevent these in Firefox and just have Firefox update seamlessly in the background like other browsers?

I'm using Firefox v136.0 on a Windows 11 host.

Each time I open Firefox the software prompts me two times (via a dialog) to enter the primary password. (I previously enabled and defined a primary password.) I'm also prompted twice to enter the primary password when I open the Firefox's SETTINGS page. This happens in "regular" and SAFE mode. I do not have any extensions installed nor themes installed/enabled. The only plugins that are installed are "OpenH264 Video Codec provided by Cisco Systems, Inc." and "Widevine Content Decryption Module provided by Google Inc."

When I delete the primary password, the browser does not prompt me to enter the primary password on startup or when opening the SETTINGS page.

FWIW, I've tried the following sequence, but the problem persists:

1. Uninstall Firefox
2. Delete as many temporary files as I can in $HOME\AppData\Local\Tmp\
3. Delete $HOME\AppData\Local\Mozilla\
4. Delete $HOME\AppData\Roaming\Mozilla\
5. Reboot
6. Reinstall Firefox
7. Open Firefox and add a primary password
8. Close and reopen Firefox

When I reopen Firefox, it prompts me twice to enter my primary password. When I open Firefox's SETTINGS, I am prompted twice to enter the primary password.

Any suggestions as to how I can convince Firefox to not prompt me twice for the primary password when opening the browser would be appreciated.

I use firefox beta and noticed that firefox always closes exactly when a new hour hits. The moment it hits say exactly 4:00, 5:00, 6:00, or so on for every hour of the day, the app crashes. I also tried this on the standard firefox and the same thing happens. I even decided to alter my device time in settings and set the time to 11.59 only to have the app crash the moment it turns 12. This is the same for any other time of day I set. I tried changing battery optimization and storage restrictions/optimization and nothing seems to work.

Hey everyone,

I’m running into a frustrating issue with Firefox. Whenever I paste a large amount of text (especially code) in one go, Firefox freezes and becomes unresponsive. This happens frequently in various web apps like ChatGPT and Make.com.

It’s not a one-time thing—it happens consistently when pasting large blocks of text. Has anyone else experienced this? Is this a known issue, or is there a way to fix it? Any tips or workarounds would be greatly appreciated!

Thanks in advance!
