Super useful addon!! the new v6.3 (webextension) works well in Waterfox56.
For Palemoon/waterfox the extension v4.6.5 works well and even includes more option than v6

Just best of proxy management extension, I have used this for more than 10 years. Eric, is there a plan to add the pattern subscription feature back?

Добавьте возможность использовать\отключать прокси по каким-то внутренним признакам (по имени компа или подсети).
Настройки синхронизируются между машинами, но одна из них не может использовать прокси, так как находится на стороне прокси.
По имени компа если получится отключать прокси - будет отлично.

именно то что искал и не мог найти:)

Greats

It's working well.It's hiding my IP. Great.THANK YOU!

Took a month subscription a few hours ago as a kind of a trial. I tried a few other addons but this one works at my satisfaction. It works fast, the fastest of all addons I tried before. Easy of use. Just add the provided IP, nickname and port. That's all folks. After expiration I will extend for at least 3 years. I'd recommend it for sure, 5 stars aren't sufficient.

good

Great features, works amazingly well. If you have to deal with switching proxies for any purpose, this is definitely the tool I would recommend.

FoxyProxy is an indispensable extension for me. In fact I waited until FoxyProxy was available that I made my final decision to upgrade to Firefox 57. I'm grateful that FoxyProxy is live and going strong with every new release on Firefox Quantum. Thank you FoxyProxy developer!

Not as good as the previous version, but it still works as intended and the dev is working hard to make it better. Would recommend.

powerful and easy to use
