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.

The only thing missing imho is All-In-One Sidebar integration, and it will be perfect.

Stylus can not be exported from backup if it is multi process.
can not export from backup unless it is a single process.

Except for the problem in the title, this seems to work perfectly! Loved this on Chrome as well, glad to see it here.

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

Works. For now.

Stylus arrive enfin sur Firefox, ce fork de Stylish tombe car l'addon d'origine ne progresse plus sur Firefox et lorsqu'on voit ce que devient Stylish sur Chrome avec le nouveau développeur, je n'ai pas trop envie qu'il arrive la même chose sur Firefox (addon dysfonctionnel, vente de donnée personnelle à une société de tracking). Stylus a encore des problèmes de jeunesse sur Firefox, on ne peut pas exporter les données par exemple. Mais avec le temps et les futures mises à jour, cet addon aura la même qualité que sous Chrome et sera une excellente alternative à stylish.
