Surfshark has excellent working apps for Windows and Android giving great flexibility, control and put the whole system behind the VPN not just the browser. I gave both of them 5 stars. I expected the same with Linux but it refuses to install and I want my whole system to be behind the VPN not just my browser.
PIA gave me all of the above but I gave it up because it was bought by a company that made its money creating spamware and then sold itself to Kape Technologies, Kape mainline of business is creating spyware for any government willing to buy its services. I must say that Kape has a dry sense of humour as it promises it will protect the privacy of its users (and will respect them in the morning?). Check the link below:

I want my PC to be entirely behind a VPN not just one browser.

Relatively easier to connect compared to the standalone Win app, lessening connection error and downtime. However, lacking more comprehensive options such as the Kill Switch.

I have reported to their online chat that their addon is leaking WebRTC but they insisted tested on ipleak.net which is fine. Worse still it reflected that it even leak on their own webpage for WebRTC test site. No details follow up to which i have urge for an updated to resolve it. We paid for privacy and it has even went through the security audit lately published on their webpage. Find it hard to accept it.

When I sign of for a VPN, Firefox add on should not block it

Ne fonctionne pas, refuse de se connecter à mon compte.
Doesn't work, refuse to connect to my account.

Ne se connecte pas...

Disconnecting all the time and doesn't reconnect. Crap... lost money....

Probably the worst paid service providing addons that not working, in firefox addon disconnects randomly and doesn't connect again, telling you that you have a network problem... tested also and in chrome and does the same. Keep your money for another VPN if you hate the apps and you want only the addon.

L'extension fonctionne assez mal sur Firefox contrairement à un navigateur basé sur Chrome : Sur Ipleak, on voit que la redirection ne se fait pas; il faut se déconnecter et se reconnecter pour que cela fonctionne.

It disconnects randomly, something you can't have on a vpn service, if it at least had a kill switch feature like on desktop.
