Random website popping up while using Firefox.

more options

When browsing in some websites such as "facebook.com", "mozilla.org", "lenovo.com", I sometimes get a popup to this link, but I don't have any kind of extension that could be causing that I think. What would be a way to troubleshoot this so that I can prevent that from happening? It's really annoying and the site also seems really sketchy.

Sounds like an add-on issue. You should manually disable all of them and then bring them back one by one. Enable one and restart Firefox, enable one and restart Firefox, until you see the issue.

I just tried Safe Mode. The issue doesn't seem to come up

I think I've found the add-on that was giving issues. I'll see if the issue will go away forever as it was something that used to be pretty random.

Thanks for the help!
