Thank you for review.

I do not collect any data at all.
“Recommends" are given by mozila officials on their own initiative.
There are many safe ones that are not marked.
If you are unsure, I recommend that you analyze this add-on.
JavaScript in this add-on is not obfuscated.
Also, the code is available on Github, so you can check it against the code to see if any illegal code has been inserted.
