Firefox uses a lot of RAM even for less number of tabs opened. Earlier it wasn't like this and I have been using firefox since 6-7 years. Please look into the issue, there are always multiple FirefoxCP Isolated Web Content that takes up the entire RAM on my macbook pro.

Just to add one thing, right now not many tabs are open in firefox. Typically I have around 35-45 tabs open but I have been keeping that number down since I saw the memory usage of it. I just want firefox to use less memory because even right now like 13/16gb RAM is used and the only open application I have are whatsapp, firefox, terminal and notes application.

Hi there! Could you try running Firefox in "Troubleshooting Mode" so that we can eliminate the possibility of add-ons being the issue? Some details on how to use it are here: https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode
