I'm having problems since this afternoon (Sunday) with the NordVPN extension,version 2.30.2 updated 24th of May when I click on it a small screen comes to log in after that a screen appeared your logged in succesfully although nothing happens as I click the extension I see the same screen to log in again and the extension also stays light grey (not activated) I tried reinstalling the extension several times even reinstalled firefox,close all extensions all same result
I saw however that several more people here have the same issue with the extension and it's behaviour as I have,so I think since it was working fine before the new relase on Sunday it has something to do with the extention itself and not something on my end here,as this occurs on both my desktop pc and laptop but I hope it will be resolved soon as this is very annoying I also contacted support.nordvpn.com no solution ! I told them to look at the reviews here where many people have the same issue as I have : not being able to log in the NordVPN extension and activate it,I think the new extension is faulty because when I changed it to an older version of the extension 2.29.1 every thing works just fine again !
this is the link to the older versions ======
