Malicious Pop Ups
When I click on links on websites, even Mozilla website, ad pop ups appear. There are no tabs open with sites that would do this, and it happens on click. Only in Firefox, not Safari. I tried the reset browser thing, not working.

Check your system for adware/malware.
Go to the Mozilla Add-ons Web Page {web link} (There’s a lot of good stuff here) and search for a good add blocker.
