The extension works great, however I had issues with the desktop app using the latest Ubuntu OS. I logged out one time and never was able to login again. I could use the static set up up configuration wireguard settings in the OS but the app itself never worked again.

Surfshark has been great for me, with one exception. The app is brilliant and easy to use. It gives me all the features of a good VPN product, BUT, ever since they introduced their CleanWeb and antivirus features, it has become a nightmare when you click on links on web pages.
Surfshark blocks everything - you just get a blank screen. There is a Bypass List feature, but it does not work on most sites. My only option is to use another browser/PC that does not have Surfshark installed and things work every time.

To be honest, compared with the nordvpn extension, this extension is just junk. Very unstable proxy performance.

Makes not knowing who I am when It is working.

Absolute garbage. the customer service is non existent and canceling a subscription is next to impossible. The online FAQ just keeps redirecting to itself and any link to do their "live chat" is fake. The advertised 24/7 customer support is a lie and you'll be asked 3 times to fill out a survey about why you want to cancel just to be again redirected to the FAQ. Email is the only way to get even a automated response just to again be linked to the FAQ and a survey.
