This is the absolute GOAT.
I use it to get around GDPR blocks and access scientific journals through my university without a hassle.

very nice! The different proxy for different websites is very useful! I haven't find this function in other addons, even foxproxy and omegaswitch.

I registered for a mozilla account just to rate this addon. It's one of the best quality addons that I know. Thank you.

не хватает работы с прокси-листами, а именно 1) отслеживание страны 2) поиска по странам внутри списка 3) проверки работоспособности прокси-листов по локальным спискам или из интернета

非常好用，感谢开发者。

I installed SmartProxy 0.9.7.1 on Firefox 84 & Windows 10 20H and added an proxy server as 127.0.01:8100 (Goflyway local proxy port), it was unable to access google.com, facebook.com through SmartProxy. But when this add-on runs normal on web browsers like Chrome/Edge, everything is fine. I don't know what's wrong. So sorry for the star rating...

Excellent add-on with very granular options and rules! Keep up the great work Salar!

GREAT ADDON/APP!!!!!! CONGRATULATIONS!!!!!

This addon cannot be installed on Firefox 79 for Android. Any hope this can be fixed?
