Edge browser 100% CPU, requires Force Quit (macOS Mojave and v91.0.864.48)
I'm reporting a problem I've experienced with Edge since I began using it six months ago. After using Edge for a few hours, it will begin using 100% CPU. According to the Task Manager, it is the "Bro...
What I do not understand is why the Edge task manager is not able to identify the specific tab or process responsible for the leak/spike. I will try to get a capture (running safari today), but when I had to kill edge yesterday, the process identified as "browser" was the highest CPU/Memory usage; none of the other tabs, add-ins or internal processes (pre-rendering, network service, storage, etc) even added up to the total indicated in the Edge task manager.
Usually, I find that closing tabs has no impact right until the last tab. On one occasion about a month back, the CPU decreased gradually with each tab closure, but the Edge task manager still showed only Browser. It's possible driven by some issue affecting the browser code managing tabs, rather than the usage of any individual tab. Most of my open tabs are sleeping anyway as I have quite a few open for convenience.
