I use Process Explorer here, and I'd love to know what you were looking at. See the attached screenshot of the Firefox Quantum processes displayed in PE. Tell me which you think represents extensions?
Chrome makes that simpler - everything in Chrome is a separate OS process - the browser itself, each open tab, each installed extension - and it's easy to see what is taking what RAM. Chrome provides fine grained control at the expense of system overhead. Processes are relatively expensive, as they must be created, maintained, and terminated by the OS. It's why programs that must have multiple things going on normally use threads instead of process, but threads have limitations that make them unsuitable for this.
Quantum uses a different model that I explained earlier. It uses less system overhead, and a goal of Mozilla going forward will be increasing the granularity of content containers to provide better control over usage by open tabs. But meanwhile, one complaint about Quantum under Windows is that it doesn't provide the additional information to let things like PE clearly identify just what those various sub-processes are.
Agreed about the superiority of uBlock Origin to ABP. I never ran ABP. I'm not that fanatical about blocking ads, and didn't care for the overhead involved in using it.

I'll have to give up Firefox then because Quantum was my problem. To check for an extension hog open up task manger or Process Explorer and open Firefox then disable one by one. Restarting the browser each time of course. It's a tedious process but can help you track it down. You can also use the performance tab in task manager as you troubleshoot. I'm using FireFox 53 and no more problems with CPU/Memory Spikes. My friend showed me how to use the performance tab in task manager to find the problem. Quantum is taking up 60-100% cpu just on open then goes back to normal till I do something else then spikes back to high CPU usage, settles down then spikes again. This happens over and over. 53 is barely a blip on the radar. It's nice to have my fans quiet for a change.
