Hey, So I'm using FireFox on my Mac, and I'm unsure what is going on here, but at random times I am getting ad's on my screen that are not part of the website. Like a google sponsored ad, or it randomly forwards, after clicking a common link, e.g. reddit /r/ link to see a comic or whatever, to a spam site. I've tried to clear cache, cookies, login, etc, and when I do it, it freezes and asks me if I wish to stop a script. Each time I try to clear again, it's a different script. Is there something in terminal I can run to find what this program is, or something I can install to scan?
