Judging from GP's description of how extension IDs work in Firefox, I wouldn't be surprised if LinkedIn were trying to brute-force those UUIDs!

If the two are indeed "Linked", I see a case for users-first browsers to show system metrics right along the page.

I've noticed similar issues with the web version of MS Teams.

You can actually see what tabs are hogging CPU by pressing SHIFT-ESC to open the task manager (about:processes) inside Firefox.

Considering the app was a battery catastrophe I’m confident in the latter, even if your question could be read as rhetorical.

It’s probably some feature they sell to recruiters to grab your attention. :)

Maybe it's trying (and failing) to access your browser extensions? In a loop?
