la rapidez para cambiar de proxys y que te permite almacenar tu usuario y contraseña, pero no te deja escoger el mismo proxy para varios protocolos

It keeps remote host from controlling what I do

Latest version requests permissions to delete browsing data. Why proxy management software would do that?
Please move that function into a dedicated plugin and use only necessary permissions in each.

UPDATE:
I'm not worried about a plugin stealing my data. I just don't want to have a bloated do-it all plugin, that uses permissions it does not need.

I agree, that different contexts when using different proxies may be useful, but that is supposed to be done with https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/contextualIdentities and not with data deletion. Even then, it's probably a scope of a different dedicated plugin.

I would also like to point out, that if you decide to remove browsing data access later, it will be a removal of a well-used feature (and much more users will come yelling), while now it is an addition of an unnecessary quirk.

To be less negative, let me say it in a different way. I adore the simplicity of previous version, with a little bit of UI polishing it would easily become my favorite plugin. Please don't take that true quality of a dedicated tool from us.

Please consider reverting the new Cookie permission requirement. I prefer this add-on to be solely resposible for handling proxy connections.

Why would I want to allow a proxy switcher to clear my recent browsing history, cookies, and related data!? A proxy switcher should only make sure the appropriate proxy is used nothing else.

Why does it need to read history and cookies?

Why does the latest version require Cookie and History permissions?

What's up with the Cookie and History permission?

现在这个只有英语的，没有本地的语言？？？

Can you comment please on support for android version of Firefox?
It installs okay, configures etc, but it does not look it works. Websites still show home IP.

It works really nice for Windows version of the Firefox.

It's a very useful extension

Pretty pretty well。

The go to FireFox extension for managing proxy connections. I have been using this extension for years, and it's still the best tool for the job IMHO...
