Does not recognize valid log in details rendering it useless. I can log into the site & with my account open on the very same web page the app tells me I have the wrong log on details.

extension doesnt work in firefox - unable to log in. I am logged in in desktop app and in my account on web, but theextension doesnt accept the same login details for some reason (copied from password manager and doublechecked)

It is impossible to log in. That aside, the addon just sucks compared to just using the wireguard config files from Surfshark (that they hide quite well).

not working and not 3.19 show in the website

Its just a garbage VPN. I spend more time touble shooting its connection than actually doing what I want a VPN for.

I cannot wait for my surfshark subscription to end. This "service" has been the worst.

keep asking to re-login. is there a problem with the firefox?

It's just way too slow to be usable

Can not login in China

As others have stated in reviews here, this extension does not work properly - it causes delays or completely fails in accessing sites, both problems of which disappear when you pause or turn off the extension. Before I am told to contact support, I have already done that and was advised to reinstall the extension, which I did, with no change. I was then asked why I was using the firefox extension and it was suggested I should just use the desktop VPN client - for a couple of reasons I do not want to do this. My next step will be to try an alternative VPN if Surfshark can't fix this. This is a relatively recent problem so someone has done something to mess things up - when you find them, can you please tell them to undo what they did.

For about a Month, whenever I start Firefox extension and connect to VPN, it is fast for the first 5 minutes then becomes terribly slow beyond and in some cases not even working anymore, and it happens very constantly. Because it disconnects from the static IP-Address and from the connection overall. Same problem as many users i read here. It used to work great with my terminal connection and the web extension but for a month this seems just not to work anymore . I tried to reinstall so many times and its still persists. Tried to get support in on this but couldn't find any proper way to contact them other then their build in bot that is not that helpful with issues like this. The service is great and the terminal connection seems to work great but this about their firefox extension which is terrible for about a Month or so and it seems that they can't fix it or don't want to fix it.

From about two or three weeks ago, I found that whenever I start Firefox and connect to VPN, it is fast for the first 5 minutes then becomes terribly slow beyond, and it happens very constantly. There is not the same problem on Chrome. I've contacted with the support service but no suggestions help (request #4257080). I believe it is the problem of the Firefox extension itself.

It seems the problem has been fixed.

Nah... problem's back, disappointed. I'm gonna use another VPN.

It worked just fine and recently(2023/1) the speed is down to like 56k modem connection. Reported this issue to the customer service and the answer I've got is "Sorry, there is no fix for extensions" And all I can do is just to endure this until I give up or pray for things going well. GJ Surfshark.
以前都正常運作但最近(2023/1)慢到簡直要吃屎，去跟客服說得到的答案是抱歉這插件沒修復方法。所以我只能忍耐。使用這之前請三思
この前に問題なく使ってたが最近(2023/1)のネットスピードはくそくらい遅くなったのでカスタマーサービスと連絡したら「すみません、修復の方法はない。」と言われた。我慢しかないと同然の答えに呆れてどうしようもないの自分がここにいる。このアプリを使う前によく考えないと痛い目にあうよ。

The Firefox extension is broken. The VPN service works correctly on the desktop app and other browsers, but on Firefox the speeds are horrendous and there are frequent errors (proxy authentication error, not logged in error when logged in, general unresponsiveness.)

Не работает в РФ, верните деньги за подписку на 2 года. Проблема массовая, набрали денег и теперь занимаются отписками, проблему не решают.

Internet connection is so slow when VPN is used, but it works perfectly fine on Edge so please fix it on firefox please.

The worst update ever!!! Proxy error all the time....

Не работает в РФ от слова "совсем", где-то примерно как месяца два. Поддержка морозится, говорят устанавливать только отдельно на устройство и будет работать. По ходу, расширение накрыл РКН, т.к. ближайший для России сервер был сначала в Грузии, а потом стал в Украине. Делайте выводы. Не рекомендую к установке. Средства не вернуть уже.

Dosn't work as an extension, even can't login
