It's a brilliant VPN if you pay for it. I have never used the 'free' plan but clearly all the 1-star reviews are from those who have. Obviously a 'free' VPN plan isn't going to be good, they never are. You get what you pay for and privacy is definitely worth paying for.

Cant connect to any VPN with free plan.

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

L'extension firefox refonctionne
Cliquez sur "Exécuter dans des fenêtres privées" avant de se connecter a mon compte Proton semble faire planter (?) l'addon (testé plusieur fois)
Une réinstallation -> connexion au compte proton -> puis aller dans le manager d'addons pour indiquer que protonvpn peut s'exécuter dans les fenetres privées, fonctionne

what is the point of free plan if you cant connect to any vpn

Free my sweet butt

Scam

no countries in free version

Absolutely a disguised advertisement - the extension never does what it says - even after creating an account, verifying and logging in, the extension never displays a connect button and only says unprotected with a big upgrade button. Super irritating to waste so much time trying to set preferences and setup an account. Should be barred from the addons or forced to fix it.

not free

Not free

Плати, а уж только потом сможешь опробывать! И ни каких гарантий, что работает.

Does not work at all.

Claims to have connected the moment the browser loads but in reality it hasn't connected and is blocking all traffic. When you click on the extension it shows a loading circle for eternity and never loads a single thing.

The only way to restore a connection within Firefox is to disable the extension completely.

used to work fine, but recently just doesn't connect anymore
