So, I restored Firefox to default. First order of business: ADP.
I go to adblockplus.org, and it gives me this wonderful message after I hit the "download" and "allow" buttons.
"This add-on cannot be downloaded because of a connection failure to adblockplus.org"
Nothing else. Just that. So, I went to Firefox add-on area and added it that way. It booted up just fine, and it's on my toolbar: magically, however, it does not work. I'm still getting ads everywhere, especially youtube. WTF? Why can't I download from the site? I scanned for malware via MalwareBytes. Doing the same thing with Avira.
I don't know how to make ADP work again. :c
