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 have been using the free version for over a year, and never experienced low speeds or any other problems. Great extension

It works, fast and faultless

Awesome, completely negates the need for a Linux client

Never had a single issue with it. Fast and reliable and, most importantly, secure. Proton ecosystem is unrivaled by anyone in the privacy scene.

Works perfectly well
