[Feature] Custom Proxy

[ncorder]

Hello everyone,

I hope this message finds you well.

I occasionally use a personal SOCKS proxy with my web browser. Currently, to do this users have to manually disable the extension and reconfigure the settings each time.

It would be immensely beneficial if users could add a custom proxy to the list of available locations.

This functionality would streamline the process for users who frequently switch between network configurations and enhance overall productivity.

No. There are third party proxy extensions to use for a mix of mullvad and others. This would needlessly add confusion to a MULLVAD extension.
