Not useful in China

Too lazy to register.

should've listened to the reviews. this might be the worst VPN in existence. to anyone considering surfshark: DON'T DO IT! you'd be lucky to get a connection 50% of the time. "proxy connection error" should be surfshark's tagline. what a waste of money.

Unusable, keeps disconnecting every few minutes. Even when connected, pages don't load or load extremely slowly

Only on Firefox, fine on Chrome

The new update sucks. Stop trying to do everything. I don't need your ad blocker/popup blocker/data breech alert/malware alert nonsense. I have other stuff for that, and historically, you do not do a good job at working cooperatively with other programs.

And now, instead of a quick click to turn on the VPN in my browser, I have to do multiple clicks to turn that on because you're trying to push this new trash on your users. I just want the VPN. That's what I'm paying for. The fact that you're pushing your other nonsense SO HARD at the expense of you know, the actual VPN services is absolutely ridiculous.

(Updated in 2022/11/14) This addon is still very terribly unstable. I'm living in Taiwan, and network environment is quite speedy when without VPN, but after enabling Surfshark VPN in Firefox, the experience becomes a nightmare: the network often becomes very slow (Even though the servers I selected shows the loading are quite low, < 25%), or unexpected disconnection and shows some unreasonable error message (for example, it often shows "your subscription is expired", but my subscription should be expired in 2023/06). Whenever I encounter such problem, what I only can do is restarting Firefox, this is the only addon I'm using with the most ridiculous quality.

If you rate 1 star to this addon, no matter how detailed is your issue description in this review, they always reply and ask you to contact their supporter via live chat or email, but if you really do contact with their support, the only thing they are going to do is to merely ask you to reinstall the addon and try again, and you will find nothing improved at all. LOL.

(Updated in 2022/04/14: In 2022/03/01, the reply from developer ask me contact to their Customer Support via Email, and they ask me to reinstalling the addon. So I reinstalled, however this doesn't solve the problem at all. It just logged out immediately when I click on addon's icon in 2022/04/14. Ridiculous. ) This addon may suitable for some unimportant tasks such as watching Netflix, BUT this is DEFINITELY NOT SAFE for sensitive data. Because this addon gets red text "error" in the popup UI frequently and cannot work at all until I restart my Firefox, sometime I have to restart my Firefox more than 5 times in a day. // THE TERRIBLY WORST PART IS: sometimes, when mouse hovering on the toolbar icon, it shows colored "connected" so I feel easy to work. But occasionally when I click the toolbar icon... I was astonished to find that I am totally logged-out, without any sign?! (and the toolbar icon became to gray immediately), I even donno when it logged out. What the hell is this stability for a service focused on "Security"? You even cannot make a average-degree stable addon. I have never used any other addon is unstable like half of this one in recent 10 years.

Fake. Selected "Canada" and IP from Frankfurt or France

Not happy. Lets me download, register etc. only to find out they want to charge me. They SHOULD BE OPEN ABOUT IT. You can't even try it without entering your credit card details. Thanks for wasting my time.

After installing Surfshark it seemed to work perfectly until, using various DNS leak test tools I checked it out. Although Surfshark showed the connection to be secured ALL DNS leak tests revealed my true isp. I was not protected at all. A BIG wake up call. I am willing to concede that perhaps there is some peculiarity to my system but I urge, in the light of my experience, regularly PERFORM A DNS LEAK TEST before going further.
I have uninstalled the extension and rely on my paid desktop Surfshark subscription.

Does not work if other VPN extension are installed. Poor programming I guess as other VPN extensions don't have a problem with Surfshark.
