Firefox eating up a lot of RAM

more options

I have been using firefox since last 7-8 years. I need had any issue until last few months. I have noticed firefox eating us a lot of RAM(more than 50% while doing nothing at all, no tabs other than the homepage). The only reason why I have never used Chrome till now. I have tired Microsoft edge and Brave. They don't have such issue. Whenever I open firefox, my laptop fans gets louder like I am doing heavy gaming. (Tested on my 2 gaming laptops). Opening firefox seems like a cpu intensive task these days. Please suggest me how can I fix these issues and stay firefox other than switching to other browsers.

In the attached screenshot, see the ram usage. And my fans are loud. I have only this support page opened right now.

Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

When I came back to firefox to reply u, the fans were quite but the ram usage was about 5-600mb. After troubleshooting mode, it came down to 350-400mb. Is it considered solved?

Sth is wrong with GPU. There is Webrender (Software) composer. It uses CPU, that's why your fans are working hard.

These issues never existed before until some recent months. How come these happen on both of my laptops!? so no solution?
