I'd love to see more linux compatability in the Proton suite as a whole.

It does its job. Reliable. Not greedy, the free version is quite good.
However, there are some problems specific to Firefox.
There are regular connection problems.
-It always says there's a problem connecting your account, but your account connects (this isn't a huge problem, it's just confusing for some).
-Sometimes it connects and then disconnects after a split second. You have to wait a bit. (Meh, okay, but it's still a problem)
-Sometimes it doesn't connect automatically (this is a minor issue if you've pinned it to the top right, but it's very annoying)
-Loses the browser permissions?? You have to delete the add-on regularly and re-grant the requested permissions. (This is what's frustrating because the necessity of this can be forgotten.)

At least I experience these problems in both Windows and Cachy.

The extension itself is super snappy and responsive, but the fact that I have to disable and re-enable it on every PC restart is driving me crazy. Otherwise it refuses to work, either saying that the destination is unreachable or showing that it is connected when it clearly is not.

Where do I submit bugs? After every time my laptop hibernates or sleeps, I have to uninstall and reinstall for the connection to work again. Or wait a very long time. I use this extension, because the official Linux package apparently requires systemd and fails.

this is a great product but a recommendation would be to have it 'talk' to the desktop app or at least have an option for it to do it that way if i connect on the desktop app its shown in the extension and vice versa. additional similar to the android app a way to set a different default connection that isnt the fastest in both the extention and linux app would be nice (i believe the windows client has this option)

Oblige à désactiver puis ré-activer systématiquement au lancement de Firefox après une mise en veille de Windows, sous risque d'exposer mon adresse IP.

Mi riferisco al servizio vpn offerto da Proton. Su Windows tutto bene mentre su Linux, UbuntuStudio e Linux Mint, ho diversi problemi che sono risolvibili ma fanno perder tempo

This is an easy-to-set-up VPN to use, with a well-known privacy-oriented company, and it's fast, i.e. the speed drop is not at all noticeable even with the free (non-media) bandwidth.

Unfortunately, if the extension is kept running while the computer goes to sleep, etc., the internet connection for the browser becomes unstable, including not being able to connect to any website. Turning off the extension restores the normal connection, but turning the extension back on still causes problems. At this point, removing and reinstalling the extension is required to get it working again. This is non-ideal. Some other reputable VPN providers may be easier to work with than this.

Good extension, but I confirm the bug reported by another user. If I close Firefox (Ubuntu snap) with the VPN connected and shut down my computer, at restart when I launch Firefox there's a notifiation indicating that the VPN is connected but the browser cannot reach any website and the extensions seems broken (blank menu on icon click). The only way to retrieve a working Firefox situation is to unistall the extension (if only disabled, Firefox stops working when reenabled).

Edit: A full re-install doesn't seem required, if you go to manage extension > disable > enable then it seems to make it work again.

Sometimes bugs out and requires a full re-install to work again.
From my limited testing it seems to be related to closing the browser while the vpn is connected.

Handy extension for tunneling your web browsing through a VPN. On Windows the extension reconnects when the system wakes, but on macOS* the extension gums up the whole browser if the system went to sleep with the VPN connected, necessitating unloading and reloading the extension.

* Intel-64 architecture; have not had the problem since switching to Apple Silicon

1. Can not specify favorite countries. You have to search a list of 900 countries, even though everyone mostly only uses a handful of them.

2. Can not be enabled only for specific *containers* (to specied countries.)
This is also easily possible with other VPNs via the Mozilla Container extension, if you would have a SOCKS5 proxy address. to use with Proton...

Other than that, it works.

This works well on desktop Firefox, but not mobile (I tried force enabling it, but it just gives permission errors so far — maybe I'll figure out it).

The Proton VPN extension is almost perfect, but on Firefox Linux, this thing just won't reconnect after coming back from sleep! Disconnecting and reconnecting hangs, and that gets nowhere, but disabling and re-enabling the extension makes everything work. Proton is a great VPN with a lot of extra functionality, but this extension needs a bit more polish.

Leider startet das Addon nicht fehlerfrei automatisch mit dem Start von Firefox. Firefox ladet keine Seiten bei eingeschalteten aqutostart des Addon und stürzt ab. Ohne eingestellten Autostart funktioniert es, daher 3 Sterne.

Worked mostly fine the last 3 weeks. Now I've had to disable it as it is blocking my connection. Hope it will be solved, but it's turned off for now.

Problem polega na tym, że to rozszerzenie w pewien sposób się blokuje. Przy ponownym uruchamianiu przeglądarki Firefox nie ma do niego dostępu, tak jakby wciąż się wczytuje, a proces ten nie kończy się. A zatem skorzystanie w pełni z tego rozwiązania nie jest możliwe, ponieważ dopóki rozszerzenie nie połączy się z serwerem, to strony nie wczytują się. Aby rozwiązać ten problem należy wyłączyć rozszerzenie i następnie ponownie je włączyć. To bardzo upierdliwe.

Try to make it work better on omegle like sites like emerald

Does the job, but it does it in the most basic and annoying way possible, for example you can't set up a default country (i.e. USA) and you instead have to constantly scroll down and activate your country of choice manually every time you want to use it because it resets the list position back to the beginning any time you click on anything...

This wouldn't be a problem if not for the fact that you can't invert split-tunnelling — I literally only want to use the VPN for one or two sites that I have data on that are blocked in the UK but I can't without it causing problems everywhere else — so I have to continuously Connect/Disconnect via the long-winded means I mentioned above every time I want to use those sites.

Other than that, no issues, but I won't be resubscribing as it's really too much faffing about for something that you should be able to set up as a one-click connect.

Hello, glad to see that these reviews are actively monitored and responded to. A major issue that I have had with this extension for ages is that I cannot pin certain locations to the top of the country list, or set a certain location as default as is possible in the mobile app versions of ProtonVPN. It is tedious to have to always search or scroll far down to get to the desired location. Please add this feature.

It never worked since I installed it like 3 weeks ago. My case is the same than the one of the previous reviewer. I need it mostly for one website. When trying to enable it I get the same error: "Network error..." Firefox and add-on are updated, 115.26.0es and 1.2.9 respectively. Not using any other proxy or VPN.

Update due to developer's reply: I'll contact you providing info on the questions asked. I would like to add that I just tried the Chrome extension and it works. So it might be something related specifically to Firefox.

Update 2: I solved it. When filling up the support request I decided to give it a last try and discovered that when installing the add-on there's a fugacious message I can't read nor accept that precedes the aforementioned error. So I recorded my screen and play in slow motion and saw there's a message asking for permissions. After googling I went to the add-ons page and selected the extension and then its Permissions tab and enabled them and it worked. Might be kind of a bug that prevents the message to stop.

While this extension has its merits, it has a critical flaw that significantly impacts its usability for me. Since last year, the connection has become unstable in China, and there are times when I simply cannot connect, no matter how many attempts I make.

Additionally, the login process requires accessing the proton.me domain, which is not feasible in China. I have to use other tools to bypass the Great Firewall just to log in to ProtonVPN, which is quite absurd. The whole point of using ProtonVPN is to access the internet freely, yet I find myself needing to circumvent restrictions just to use the service.
