Some Firefox Dev Edition background service is using absurd amounts of CPU
Having this issue for weeks now, I finally decided to create a ticket. I currently use Firefox Developer Edition, but it has some problem: At random times, a background process starts and begins to use an absurd amount of CPU. I have a really good CPU and this issue still occurs when I start my laptop without even unlocking it yet.
I'm thinking it has something to do with an update service, but I already tried disabling automatic updates and updated to the last version. I even deleted all add-ons, but it didn't help at all.
There is a strange folder in the installation folder named "tobedeleted", which gets automatically created. I don't think it is some virus because viruses would've aimed for Firefox and not the Developer Edition, which is a completely separate install. I didn't have this problem about 2 versions of Developer Edition earlier so I don't think it's my system config or antivirus/firewall.
The issue is very strange and annoying, I've tried reinstalling, deleting and removing leftover folders on the whole disk but the issue still persists. I even did a Firefox Refresh multiple times, but nothing seems to work.
I would be very thankful if this problem gets solved and I'd love to help you guys analyze the situation because I really like the Developer Edition. I have a lot of experience with programming and computers in general so I could do some debugging.
Thanks in advance!

It is possible that your McAfee security software is causing this problem and prevents Firefox from updating properly (DE updates twice per week).
Boot the computer in Windows Safe Mode with network support to see if that has effect.
Thanks for the reply, I gave the Firefox services full access on the firewall list. If that doesn't work I'll try using safe mode.
