It does not work. I tried a fresh firefox profile with no setting changed just this addon, ublock origin and Firefox container addon. I allowed multi container to change proxy settings but I get "Error! Could not connect to the proxy. Probably the settings are incorrect." but I've double checked my settings. I guess Firefox update probably broke something and this addon hasn't been updated in 3 years. I'm on linux mint if that matters.

need more features (swich profile) to customize the proxy like switchyOmega. This will make the utility even more perfect

nice and useful, but it has just one big problem: if I do not use the browser for a while, when I go back to browsing, it breaks web connectivity and I have to disable it to go back to browsing.
Until that, I can't load any page and the browser seems blocked.

Fantastic addon, I use it all the time for a variety of things. But after the most recent update I can't access proxied localhosts! One of my main use cases is using an SSH Socks proxy to tunnel to my VPN and access localhost on the server. Please fix!

Here it worked just whit local proxies (TOR and Your Freedom, apps listening on 127.0.0.1). Don't worked with external ips (that are fine with FoxyProxy Addon). Restarting browser and enable/disable addon had no effect. I disabled FoxyProxy while testing this addon.

Any tips ?
