Firefox uses 30 % or more of the CPU? How to avoid?
When Firefox is just open (without using it) it often uses 30 % or more of the CPU? Why is that? How could one avoid it?
At the moment there are about 10, 15 tabs open.

Do you have the same problem if you create a new profile and test it with no extensions or non-default themes installed and load only one tab?

Thank you for the links.
With a single tab (or even more, 3 at the moment) I do not have that CPU usage (now up to 5 %) with the same Firefox / old profile.

Then the possibility is that the problem is a matter of the content in one or more of the tabs not being opened during this trial.

Yes, is there a way to find out which tab / content might cause that CPU usage?
And what content can cause such CPU usage at all?

Videos and animations are obvious candidates. You could add one new tab at a time (from the list you had in the original situation) and check CPU usage after opening each tab.

OK, I will try it the next time. So this CPU usage definetely is caused by such a content / the website / may be bad programming (of the page / website) and there is not anything one could do against it (but to load less pages / content at the same time), I assume.

That's the likely scenario but without testing as I suggested above it's not confirmed.

There is about:performance, but I don't know if you'll get anything meaningful out of it?

Yes, may be the CPU usage for single tabs, it is displayed, do not know if it is the usage for opening the tab or while it is opened, I will try it the next time. Thank you

A miner? In the Underground? In a coal mining or so? Yes, yes, of course.
