NordVPN are still promoting its extension add-on for Android, knowing full well it is not possible to install it any more, unless using the Firefox Nightly build, with the developer options enabled. And even then it doesn't allow login, so is completely useless.

Not a good look.

EDIT following reply from NordVPN:

I wouldn't have commented here without having first raised the issue directly with NordVPN customer support.

I finally got past the chatbot and spoke with a real person, only to be fobbed off with all sorts of nonsense; ranging from an initial claim that the extension wasn't even supported on Firefox on Android, through to being unable to give any indication as to whether a fix was even planned and finally a refusal to accept that the NordVPN marketing hype, which still claims the extension is available for Firefox on Android, needed to be fixed.

So I won't be taking up the offer to waste more time with NordVPN.
