GER:
ProtonVPN läuft bei mir tadellos und ohne jegliche Unterbrechungen oder Fehler. Die allgemeine Nutzung ist sehr zuverlässig.

Einziger Wermutstropfen ist ein drastischer Rückgang der Download-/Upload-Geschwindigkeit bei manchen Cloud-Anwendungen, speziell beim Übertragen von Daten im GB-Bereich. Dieses Problem lässt sich zwar lösen, indem man das VPN kurzzeitig deaktiviert – was allerdings nicht Sinn der Sache sein sollte.

Für meinen persönlichen Anwendungsfall ist dies vertretbar, da ich hauptsächlich meine eigenen Cloud-Lösungen nutze.

ENG:
ProtonVPN runs flawlessly for me, without any interruptions or errors. General usage is very reliable.

The only drawback is a drastic drop in download/upload speed with some cloud applications, especially when transferring data in the GB range. While this problem can be solved by briefly disabling the VPN – this shouldn't be the goal of the product.

For my personal use case, this is acceptable, as I mainly use my own cloud solutions.

Great extension.

My only gripe is that sometimes it stalls while connecting and the browser cannot load anything, while the button to disconnect/connect is unresponsive. To resolve the issue I need to either disable/re-enable and restart the browser, or reinstall the extension. It's happened a handful of times so it's worth pointing out.

Still, I definitely recommended this extension if all you're wanting is VPN in the browser because I've been a customer for many years and Proton is about the only organization I'd say I trust enough when it comes to privacy protection.

I made a account just to make a review, on my issue. (hopefully this extension gets better)

I like Proton a lot. Why? Because Proton is just a amazing company in general. Their VPN is one of the best, and their free VPN is the best non-paid VPN in the market.

However, I've had some problems with their VPN extension. I have limited freedom, I cannot enable the kill switch, change my VPN protocol to something like Stealth (that was created by Proton) to bypass VPN blocks and censorship.

On a heavily restricted, locked down WiFi network (I'm talking Amazon.com, Github.com, DuckDuckGo.com are all blocked and much more), the VPN extension is blocked despite me being signed in and it working on a hotspot and other networks without restrictions. I've used the VPN app with Stealth and it's worked fine on the network, but the extension doesn't work.

I hope that this extension improves in the future and addresses this issue. Thank you Proton.

Actualización:

Los problemas de conectividad se debían al software Killer Performance Suite y Killer Performance Driver Suite UWD de Intel. Una vez desinstalados, la conexión es inmediata.


Faltan funcionalidades básicas que sí están implementadas en el software para escritorio. Desearía, por ejemplo, definir un servidor favorito al que se conecte siempre.

Proton ¿cuándo implementarán Túnel dividido con nombres de dominio en el software de escritorio?

The extension looks the part but has usability issues that need managing manually.

The main usability issue is that if you're connected to a VPN server and the computer goes into sleep mode then later resumes, the connection isn't refreshed/handled properly, effectively blocking traffic until you manually disconnect/reconnect. Occasionally this issues causes the GUI to become unresponsive too, requiring the extension itself to be restarted.

There's also no feedback given on the connection quality/speed of the server you're currently connected to. If it starts to feel slow, it requires manually moving to another server; there's no automatic transfer to a better equivalent server within the same country.

Not a negative mark on the extension per se - but it's worth noting that there's a growing list of websites that will detect you using a VPN (likely through matching your IP against IPs known to belong to Proton/etc.), making VPN usage for 'general' anonymous browsing more and more frustrating.

Proton VPN itself works well and provides lots of protections and connection configuration; it's just the extension that has a few issues really.

I need to reboot the extension whenever I switch wifi networks or else every few days. I routinely keep about:addons open so I can turn the extension off and on again. When I click the extension icon in the toolbar in this state, it just shows me a loading spinner. Besides this hiccup, the extension works great. (I am a subscriber.)

Please add an option to connect to last.

It work mostly well, but it will have issues reconnecting if the computer goes to sleep or if Firefox serivce get interutped in some way. The extentions does not seem to be listed on Proton support pages, so not sure either where to report these issues or find forums to discuss issues.

Thanks for providing a free version. Much appreciated. Wish I could pay... hopefully in the future. Unfortunately, it does not work for me on my phone :( postmarketOS on Linux ARM device.

Gostaria de um modo reverso no tunelamento dividido, pois preciso do VPN para apenas alguns sites.

Fora isso, muito bom.

Unstable connection from time to time

yet to test it, wait for the 2nd part of the review.
