how to monitor extension resource usage?
When you have the choice of multiple addons/extensions that can perform a certain task, is there a way to monitor their system resource use? To select the one which is the leanest.
I am sometimes using firefox on low-end devices. I feel that certain extensions are using more/less resources. But what's the truth?
In linux system/task monitors, you can see processes "WebExtensions" running beneath firefox. Is this reporting extensions as name suggests? If so, is there a way to correlate them to specific add-ons?
Would also like to be able to know about what extensions are doing "in the background" vs when you are actively using them.
This is about desktop versions of firefox, not mobile.

Thanks for the suggestion. I don't understand how to use this though.
For a moment there actually was info in the Memory and CPU columns but I went to another tab/window and when I returned it is blank again. If I could reproduce that, then I would be able to see resources use of individual pages, but there is nothing about individual extensions here that I can see.
If you hover the mouse each row, a little speedomoter time icon appears. It has a tooltip reading "Profile all threads of this process for 5 seconds". Clicking it brings you to a URL beginning
https://profiler.firefox.com/from-browser/calltree/which appears to collect information from the system and send to mozilla (?) without asking consent to do so.Here is the content when I clicked the speedometer button on the "Extensions" row above:
How is this interpreted?
Tangent: is anyone else finding duckduckgo extremely unhelpful these days? A search for
"about:performance"gives zero results. Is this do to having to be so aggressive against AI spam?Oh friggin Mozilla, they've dumped it in favor of
about:processes, which is useless for this purpose. I guess you could tryabout:memory, or see if any other pages inabout:aboutmight suit, but I don't have an answer for you anymore 😞FWIW if you put an !g in front of that query there's plenty of results, DDG still ain't there yet 😞
