Diễn đàn hỗ trợ Firefox

My computer (pc-windows 10) keeps freezing. Today, when this happened I launched Task Manager and discovered Firefox had opened 68 instances (I had one window open) and was using up 100% of my Core i7 CPU. I was on YouTube at the time.

I'd like to stay with Firefox as I have been using it for years, but this is happening all too often. Is there a way to limit the number of instances that it will generate?

Selecting "Help About Firefox" causes the window to appear but this window then freezes with no information. It is possible to close the window and continue with Firefox. This happen nearly always but occasionally works correctly. Current Firefox version is 146.0 but the problem is not limited this version. System is Kubuntu 24.04, KDE Plasma Version 5.27.12 and QT Version 5.15.13 I have tried several things. Deleting the .Moziila folder will permit the window to work once but after a restart stops working. Any new things to try would be appreciated.

I usually have multiple tabs open and my MacBook slows down and gets hot. Firefox is using A LOT of memory. Is there a way to have inactive tabs go dormant, helping reduce overall memory usage and improve browser performance? An advisor mentioned this is an option in Chrome. Is there a fix?

Thanks

HI, sorry my English is not so good -hope, you understand me. Since a few weeks I have a problem with firefox: after using the browser without any problem, I close my Laptop by dialing "Ruhezustand / hibernation". When I open my laptop again (regardless of duration), Firefox tabs are "grey", cannot be longer used. I have to close the browser completely and start again, very cumbersom! What can be the problem? IOS is updated, Firefox also. No other browsers have this problem. Hope you can help me? Best regards

The last couple of weeks or so (as of 121025), using Firefox is very slow. Is this another Firefox update issue, or Microsoft update issue, Norton update issue or a combination of different updates that aren't working together as has happened many times over the last few years.

Any known solutions to this new problem?

Thanks

Ron

Ever since the last update or so (I'm currently on 145.0.2), simply opening a YouTube tab is enough to bring my browser to halt. Looking at the activity monitor on my Mac shows "FirefoxCP Isolated Web Content" using an insane amount of resources, multiple instances of 101% load on my late 2023 MacBook Pro (M3 chip).

Any ideas?

Firefox prevents going into hibernate mode. It only appears to blank screen until mouse is moved or lid moved. This happened on 3 year old dell and now on new lenovo. I've gotten around it by going into task manager and killing firefox before hibernating. This doesn't happen on a newly opened window. I've noticed that as you use it, in the task manager, (not sure of correct term) the amounts of firefox tasks/threads? increases but does not decrease when tabs are closed. Eventually hibernate stops until I kill the firefox program. I thought this might go away with new lenovo with twice the ram, but happens at same rate. If I forget to kill firefox, I end up with a dead battery. This doesn't happen with edge or other browsers I've tried.
