Shows a message "NetworkError when attempting to fetch resource." and a button "update" upon clicking it, it just redirects me to the page of this extension.

As many others have pointed out, this extension is crap. It regularly disconnects so pages won't load, as in, very frequently, making it extremely annoying to use...

it just unfortunately doesn't work

Totally unreliable. Icon on app in tool bar often shows wrong status. Often hangs. Blocks after suspend and have to turn extension off then on again. As bad as Proton's Linux VPN app, wish I wasn't a paying customer.

Такая же не работающая помойка, как и на андроиде. Не рекомендую.

Not available for Firefox on Android, so I have no choice other than to skip it.

Extension has been extremely reliable for me over the years but over the past couple weeks the experience has really gone downhill, the VPN doesn't auto-connect on browser start, it loses connection very often and does not connect to a new server, and it often fails, outright saying I need to re-install the extension, which I have done a couple times now, to no avail. Not sure what they are cooking but I can't say I'd recommend the extension right, I will be sure to update my rating should this be a temporary spell.

If isp blocking proton site there is no way to use this extension because authorization is going before establish vpn connection.

Для начала работы VPN надо войти в аккаунт, а при попытке войти в аккаунт выдаёт ошибку: "При соединении с account.proton.me произошла ошибка. PR_END_OF_FILE_ERROR". Не рабочее дополнение

It works, but it's completely useless. For whatever reason it always selects the Netherlands, which is extremely slow here.
Being able to pre-select the country is a must, I think.

love proton but this is for paid only. It chooses fastest for you or you have to pay. It wouldn't even load or accept it for me to even try.

My free fastest is in Netherlands and I'm in USA.

So I guess I have to pay or it needs updated?

Cannot access extension on 115.21.0 ESR no options to do anything with application.

paying customer here. I constantly have to re-sign in again and again, this happens every few days. no other extensions active.
the worst is that sometimes I don't realize i'm not connected. other times i have to restart the browser to let me connect to the internet.
used a competitor before, for a year, none of these problems.

Якщо ви зареєструєтесь на їхньому сайті, вам на пошту буде приходити спам-розвод, де будуть казати, наче у вас троян і у вас вкрали інформацію. Це типовий розводняк, але те, що цим займається ця компанія - неприємно. Перевірити мої слова легко, зареєструйтеся з особливим нікнеймом чи новою поштою де ніде не світили, і через декілька місяці ви побачити подібні листи. Не рекомендую використовувати будь яку програму\розширення, бо я сумніваюся, що лише спамом вони обходяться.

Proton Free plan is only for 308 servers in 6 countries, probably not the country that you need.

Should appear much before I install this extension and try to signup for free.
