Firefox uploaded 250MB to a random fastly server without any knowledge from the user.
I have just caught Firefox uploading 250MB to a random Fastly server for no reason. I wasn't uploading anything i was just watching some YouTube videos. Should i be alarmed? Should i worry about this? Is it normal or do i need to check my PC for malware (MalwareBytes didn't find anything) Any help would be appreciated. Im using Glasswire to check data usage.
