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 "Browser" thread that is using this CPU. If I Quit the application, all the windows close but it doesn't fully quit; I have to do command-option-esc to open the Force Quit window (where it says "Microsoft Edge (not responding)" and then I'm able to Force Quit it. When I relaunch it and re-open the web pages I was using, it works fine (until later that day or the next day, when the process repeats).
Does anyone know how I can troubleshoot this so I can file a useful bug report?
This has happened many times over the past 6 months, over many different Edge versions (I'm always using the latest stable version). I'm not able to reproduce the issue when I want, but it happens regularly every or every-other day.
I'm using macOS Mojave 10.14.6 on a 2015 MacBook Pro.
Edit: It just happened again, so I took some screenshots and attached them below.

@quinncom same here. If someone from the Edge team is interested I used 'sample' in Activity monitor and captured a 3s sample of the process before I killed it. I keep waking up in the morning with fans on high speed. Switching away from Edge Dev to save my microchips :).

I'm also getting the same issue with my 2017 13-inch MacBook Pro, running BigSur 11.4. I also have a 3s sample from Activity Monitor, if anyone from MS is interested.

I wrote a script to detect when Microsoft Edge gets stuck at 100% CPU. It displays a notification if Edge is using more than 90% CPU continuously for more than 10 minutes. Details and instructions in the script comments:

Since my previous post, I have switched to a 14 inch M1 Pro MBP, with latest native version Edge, sometimes the problem still occurs. More often after idling for a night than normal usage during daytime.
Anyway, it should help if people can click "..." on the up-right corner -> "Help and Feedback" -> "Send Feeback".

@welsonsun Thank you for the reminder. I'll start submitting the feedack when i see this. If others submit as well perhaps it will build up enough feedback/diagnostic data for Microsoft to investigate.
When i submit feedback, it does give me the option to include attachments. I will open Activity Monitor and take a process sample and include that, and submit regularly.
Others, please do the same!

@BrianCHLiu @welsonsun @quinncom @jkristia I updated browser to version 99.0.1150.52 and i also hid my collection button in the toolbar (Appearance settings, Collections Button DISABLE, see screenshot below). That seems to have fixed this issue. I've been running for about 5 days and have not run into the 100% cpu issue again. Battery life has been fantastic.
