vopono VS user.js

Vopono (https://github.com/jamesmcm/vopono):

"vopono is a tool to run applications through VPN tunnels via temporary network namespaces. This allows you to run only a handful of applications through different VPNs simultaneously, whilst keeping your main connection as normal.

vopono includes built-in killswitches for both Wireguard and OpenVPN."

I think for now on Linux you (still!) have to use external application to do the splitting. Such is vopono

I use vopono to manage it for me with Mullvad though.

you might want to check out vopono, i've gotten it working with firefox and its nice

I highly recommend using something like vopono with this on Linux that runs only the target application (e.g. Transmission) in a network namespace in the VPN and only forwards the specified ports and only allows traffic via the VPN.

This is why I use vopono - you can run just the torrent client in the VPN on its own and the killswitch keeps it safe.

You can find the option in the settings of windows and android apps. Unfortunately, it's Still not available for Linux. As a workaround for Linux, you can use vopono, which has OpenVPN support for Proton. Or just manually add routing table entries :)

I wrote vopono, I use it all the time for quickly spinning up browsers through different VPNs for checking geographical restrictions, etc.

Re: firefox and privacy, if you want to use firefox for privacy, consider using https://github.com/arkenfox/user.js . There is a case to be made that Firefox (with arkenfox's user.js) is one of the best privacy-respecting but still fairly usable browsers.

For extensions, I recommend people follow the recommendations[1] in the arkenfox repo and either harden their firefox or use librewolf. Umatrix is unmaintained since 2019.

For macOS : Thunderbird and you can harden it even more with this : https://github.com/arkenfox/user.js

only arkenfox

This article is shit. https://github.com/arkenfox/user.js/ is what you want.

If you make time to dig through settings and change them away from their official use (99% of users don't), then you should use a customized setup (in this case, a user.js). That way, you're good to go no matter what Firefox fork you use.

> Firefox remains a stable option to come back to everytime

Don't get me wrong, I've been using Firefox for the last decade and I don't intend on using anything else for the foreseeable future, but Mozilla has no idea what they're doing with Firefox nowadays. Firefox View is the most useless thing I've ever seen, that expiring "independent voices" theme picker was some weird hippie stunt[1], the latest UI redesign which split the tab from the window looks hideous, and it's not like Firefox doesn't have things you can tweak for a more private experience[2]. I miss Firefox Test Pilot where they tried out different new features, I found a lot of them to be very useful but sadly lots of them didn't make it.

Like others have said you can customize the browser to the point that it doesn't even look like the default anymore. Or customize it to maximize privacy.
