If I understand bug 1251911 correctly, YouTube Unblocker is downloading this add-on, and then this add-on does all the things mentioned in comment #0. Is this correct, Andreas?

Comment 2

[Andreas Wagner [:TheOne] [use NI]]

Correct.

Comment 3

[Jorge Villalobos [:jorgev] (he/him)]

Taking this one since it's fairly urgent.

Comment 5

[Nico Haase]

Just out of curiosity: is there any way to see a complete list of installed addons, and not the probably "faked" one in the addon manager?

Comment 6

[Andreas Wagner [:TheOne] [use NI]]

No 100% reliable way. With this add-on, it would be visible in about:support, but as extensions can do anything, they can also hide from any place they would normally show up.

[[:philipp]]

if it's the same as in bug 1161259 the maliciously sideloaded addon might have a random ID/name

Based in forum threads https://www.camp-firefox.de/forum/viewtopic.php?f=1&t=114805 and http://www.drwindows.de/programme-tools/96150-warnmeldung-avast-beim-starten-firefox.html

There is strong indication that the following IDs are used by this add-on as well:
