User Reviews

User feedback consistently highlights Surfshark VPN Extension as generally reliable and offering good value for money. The standout pro is its Bypasser feature, which helps access sites or services blocked by VPNs or country restrictions. Users also report smooth performance across tests and positive experiences with support and configurability. A notable drawback is that the extension requires registration and, in some cases, the use of another VPN to enable it, which can be a hurdle for new users.
Pros
  • Reliable and generally problem-free performance (fast and stable).
  • Good value for money with feature-rich options.
  • Useful bypass feature (Bypasser) to access sites blocked by VPNs or country restrictions.
Cons
  • Requires registration and, in some cases, using another VPN to enable the extension, which can be a hurdle for new users.

Give us an option to turn off the RED warnings. I don't want to use any of these other settings and I don't want large red text warning me every time i click on the add-on, which takes up 1/4 of the freaking screen.
