using Surfshark on linux sucks, the service works very well on android and windows, but on linux is a lot more insecure, inclusive when I make tests on the official page, the result is that there is a DNS leack and the solution is buying the service, but the funny thing is, I already have the service activated.
And when I use chrome extension the leacks dissapear but on firefox extension I can't even access the account. The service has potential, but it needs a lot of improvement to work properly on linux.
