So as far as I understand, the Stylish plugin's last update was at August 9, 2016 , and because of Mozilla's policy not to let information gathering for the extensions that you can download from mozilla.org, they (the owners of Stylish) really don't have any incentive to make a newer version for Firefox.

So yeah, thanks and keep up the good work!

I am extremely happy I found this one, I was worried about my ability to continue to customize my web browsing experience since it doesn't seem like stylish respects privacy anymore.

Schomery and tophf, I would like to thank you for looking out for those of us who still care about these issues. I can't wait to see what else you have in store for Stylus.

Moved from Stylish and all seems well. Thanks for porting :)

Works. For now.
