It works, one have to allow it to run in private tabs

Супер! То что надо! Работает исправно!

It worked flawlessly on my Win10 ThinkPad. On Archlinux IdeaPad, it did not. Despite filling socks proxy on localhost, whatismyip.com kept showing that I'm not connecting via proxy. I disabled this extension, configured firefox native settings to use proxy and it worked. So I enabled back this extension back and it started working. I can not explain it, but it seems ok now.

Does not work at all.
When Firefox starts, the icon does not match the selected mode.

Does not work, does not switch proxy at all. Useless.

Nice and useful add-on! But the color of the icon on the button is displayed incorrectly when the browser starts. And it would be nice to make the automatic selection of the proxy mode when the browser starts.

This add-on contains all the necessary options for "normal" usage, that is, when you need to access the Internet through a specific proxy. It's almost the same as setting the proxy on Firefox's options, but much easier, with the added functionality to black list (exclude) sites that require direct access. It's reasonably light on resources (less than 200 kB in size).

very good, works well, easy and useful.
and :
1, how to disable notifications when switching proxy? feel it is not necessary.
2, could you pls add a function to easily switch between several manual proxies, eg. 127.0.0.1:8458, 111.111.1111.111:1111, etc.

Does not work with PAC correctly

doesn't work... It didn't seems to behave like if manually updating proxy setting.

doesn't work for me, sorry, when set on "direct" firefox is still using the proxy. Thanks anyway.

Simple, but it works!
