Extremely high Cpu usage after firefox update
Hello, I hope someone can help me.
Ever since I updated firefox, my cpu is almost at 100%. With only 2 or 3 tabs open. I updated from version 106.0.2 to 112.0.2. Before this update, I could have several tabs open, up to 10 and the computer would run fine. Now with 3 tabs open, it gets really slow. And I can hear my desktop suffering (the fans go to full speed). When checking the task manager, firefox is taking all the memory and the cpu usage is almost at 100%. I have to keep restarting firefox.
The conditions are the same. The only thing that changes was updating firefox. I already searched for ways to reduce the firefox cpu usage, but nothing changed.
Is there a way to fix this? Or how can I go back to an older version of firefox? Because I'm afraid my computer will die from simply opening 3 tabs.
Thank you in advance.

You can create a new profile as a quick test to see if your current profile is causing the problem.
See "Creating a profile":
If the new profile works, you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

- What add-ons do you have?
- Is GPU working? Enter about:support in the address bar and check the GPU Process row in the Graphics section.
You can check the about:memory and about:processes pages for info about all processes. There are several toolkit.aboutProcesses prefs on the about:config page to show more info. See also the about:unloads page for info about the tabs.
maybe one of the websites you are using causing this problem if that is not your problem try updating your computers software

Thank you for replying. I have the ad-ons Kaspersky protection and ublock origin. I've had these for years. The Gpu is working. In the GPU Process it says: default available
In the about:processes page, the gpu's memory is 254mb and 0.50% cpu.

Thank you for replying. Although, I'm not sure what I'm suppose to do with this information. I have sorta basic knowledge on this.

Thank you for replying. The software is up to date, and it happens on several websites.
This morning my computer froze completely. When task manager finally opened, it said firefox was using 6000mb. The website open was aliexpress, with 5 tabs.
Yesterday, firefox was using 2000mb with 1 instagram tab and 3 facebook tabs open (no videos playing).

Thank you very much! I dind't knew it was possible to test in different profiles. When making a new profile, it runs smoother, so something must be corrupted on the previous one.
I transferred the bookmarks to the new profile, and added the extensions. I tested with 10 tabs open and it was ok. Looks like it's solved. Thank you!
