Firefox How to monitor tab memory usage without using about: memory?

Question

How to monitor tab memory usage without using about: memory in Firefox? It looks like the about:memory result is not very user friendly.

Is there any good tool to use in Firefox like Task Manager in Chrome to monitor tab memory usage?

Update: I just find I can use a plugin in Firefox called Memchaser to monitor memory usage in Firefox Memchaser

Answer 1

Try using about:performance. It seems to give real-time data similar to Chrome's Task Manager.

The add-ons don't work in Firefox Quantum, since the add-on framework has been changed now.

Answer 2

I use Tab Memory instead, https://addons.mozilla.org/en-US/firefox/addon/tab-memory-usage/?src=ss

Tab Data freezes my Firefox
