### Reason

YOUTUBE to MP3
https://addons.mozilla.org/en-GB/firefox/addon/youtube-to-mp3-firefox/

After adding the extension then (re)loading 
hxxps://www.youtube.com/watch?v=aLzoZxcnAV0
a click on the **Download MP3* button leads to unexpected appearance of fraudulent content in a new tab: 

hxxps://the-major-news.com/latest-articles/student--makes-125k-in-2-months/index.php?lpkey=76367aa583f0726939d8e520bfe16e96.1574321110&rdtrckcbp=1574320810&rtkcid=5dd63aaaf160b1000123c0cd&rtkcmpid=5d9c3bad8f42d900017a0d33

Fraudulent content so soon after adding the extension appears to *intentionally violate policy* so I guess, this should be a hard block. 

### Extension IDs
```
youtubetomp3@addons.youtube.com
addons-mozilla@youtube-to-mp4
```

### Additional Information
Given the similarity of the screenshot used for the extension below, I might also be suspicious of this one: 

YOUTUBE to MP4
https://addons.mozilla.org/en-GB/firefox/addon/youtube-to-mp4-firefox/
addons-mozilla@youtube-to-mp4

For both extensions, version 6.0 was released on the same day. 

The offending version of YOUTUBE to MP3 is 6.1, I did not test 6.0.
