Just found my Vivaldi update contained a little more than just bugfixes… it now has Proton VPN built in.
It’s actually part of the browser, not an extension, so I’m in two minds whether I like that… or not.
You need either a Vivaldi account or a Proton account, so it’s not completely anonymous, but it’s a start.
The free-tier of Proton VPN also appears to be bandwidth limited and your exit point is randomised, so… yeah, it’s ok…
And none of that relates to the VPN which, under Swiss law, is not obligated to retain any logs whatsoever.
