Hello,
When you say "Lies from the first letter", do you refer to your text?
Because that's what it looks like to me :D.

Permissions system is complicated, I've tried to describe it here:
https://github.com/fastaddons/GroupSpeedDial/blob/master/PERMISSION_JUSTIFICATION.md

Regarding selling users data to Facebook / Google - you think they need more data? Google literally build a Chrome, they have all the browser data they can dream of.

Note that my extension is manually reviewed by Mozilla stuff before each update, I've wrote about that here:
https://connect.mozilla.org/t5/ideas/addons-store-should-show-which-addons-are-quot-actively/idi-p/88832

Why such a hostile attack though?
I'm just a normal full time addon developer with low income that develops this addon for 9 years and you attack me here like I'm some kind of a criminal.
Why?
Best Regards,
Juraj Mäsiar
