I use it all the time for Netflix. I always find a server that works!

work great on all browsers incl Firefox. easy to use, connect/disconnect, and allows split tunneling

Really good to add site-granularity in Proton VPN

The extension is not working at all at the time I am writing a review so I am forced to use the desktop app again which cuts my internet speed to 1/4th. Review will change if this is fixed. Edit:they fixed 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.

EDIT: works flawlessly on Debian, all my issues it seems were because of Windows, adjusted my review to reflect my current experience with the product
