Even though I have 16 GB of memory, Firefox sometimes eats up lots of it and/or lots of CPU when I have many windows and tabs open.
It's impossible to find the high consuming tabs. Give us a command or display to identify which tabs are the highest resource hogs.
Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.
While there is nothing as easy as what you're describing, Firefox now has a "Power" profiler that allows you to record the activity of a tab and understand its Power usage:
Make sure if you enable this to select the "Power" setting.
There is an internal page with the address about:processes that -- at least on Windows -- allows you to see Memory and CPU usage per process, and lists which tabs are in that process. Starting in Firefox 108, Shift+Esc opens that internal page.
Hey @D4732 ,
Following up to see if our Tab Unloading feature addresses what you're looking for. Learn more here: https://firefox-source-docs.mozilla.org/browser/tabunloader/
Looking forward to hearing more of your thoughts.
Unfortunately about:processes doesn't work for you if you have something like this:https://staticblitz.com (63021, cross-origin isolated)You can't find it neither in the tabs list (because this domain is not open), nor in the about:debugging#/runtime/this-firefox because this worker (or what is it actually?) is registered to another domain.
You can't even copy its name because somebody set user-select: none to the whole about:processes table without ability to copy information in any other way.So it is working somewhere, eating up to 100% of CPU and I have no other way to kill it than closing my tabs one by one and hoping that it works.
