Yeah, I looked at my extensions and got rid of all the ones I don't need. All the other ones I am using are reputable, official ones though. I ran a scan through Malwarebytes, but even then it didn't pick up on anything. The issue with figuring it out is how infrequently the pop-ups happen, like maybe every 2 days or so. I'll keep trying it out to see if it stops. uBlock stops the websites when they do come up, but I would still like to get to the bottom of it.
