Finally the Linux version for Firefox works. And it reconnects when restarting the browser. Perfect :)
I use surfshark for a year now and I am satisfied with it. The comments below which criticize that surfshark is not free.. Free VPNs are getting their money from spying on you and selling the data - paid VPNs like Surfshark are financed by subscription plans. I hope, Surfshark keeps their fair subscription model, since privacy is the main reason for using such a VPN.

on te dis que c'est gratuit mais tu dois choisir un forfait pour t'inscrire.

Только платные тарифы...

Surfshark does not work in the country i am . It may work in countries without internet censorship. I may have just wasted my money.

Am I missing something? Surfshark makes it more difficult to do my banking and other things like that on usually trusted sites. I have to disable it to do my banking, annoying.

Since Version 3.1.0 it works realy perfect and looks good.

Take it from experience, forget the rest and go with the best. Surfshark is the best and well worth the investment especially in this day and age. Visit us at https://climatechangecommunity.com - Thanks!
