I noticed that when I run Pale Moon in normal mode, there is a permanent high CPU utilization (12-13% of a quad-core CPU, AMD Phenom-II X4, means about 50% of one core), especially between palemoon.exe and a thread running the xul.dll, just while having

What does this page do, once it is rendered?!
Permament background transfers which are to be checked by one/some of my add-ons (including NoScript and uBlock Origin)?
CPU utilization drops to 3-4% if I run Pale Moon in safe mode (thus no add-ons active, thus no network transfer monitoring).
Is there any way to profile which add-on has how much CPU utilization at the moment? If I could log that, I guess there is a chance to catch the add-on stumbling into a kind of live-lock after hours of suspicious activity. Deactivating each of the add-ons and watching the result over several hours to days in each case would only be the second-best solution, as this would take several weeks to collect results, in which I could not work with Pale Moon.
I confess, I have a lot of add-ons installed (more than a dozen); most of them should be rather passive, though, only activated by a button or shortcut. NoScript and uBlock Origin should be the only obvious candidates for being rather permanently active. At least from my PoV.
