Their Windows and Android apps are fine but this Firefox extension is actual hot garbage. It loses connectivity so constantly regardless of what node I choose or how busy it supposedly is that I eventually just give up, disable it, and then the internet works fine again. They're going to reply to this asking me to contact their 24/7 support via Live Chat but surprise, I tried earlier and could not actually load it with this extension on. If anyone is considering a subscription and are comfortable with the apps, then fine but it's better to pretend the browser extension option doesn't exist.
