Assuming you mean the Mullvad extension (which is installed by default in MB) and not the Mullvad VPN app (which also exists but never came close to these machines) :)

That will indeed likely make a difference on Mullvad Browser numbers. However for now I’m not changing the “keep addons at stock defaults” invariant or the test matrix might get really out of hand… Should we disable uBlock Origin in LibreWolf? How about uBO or NoSccript in Mullvad then? Konform Browser loads uBO but only if its apt package is installed; should we do that? What happens when we try to explicitly opt out of everything under Preferences in Firefox? I guess the last one is something to actually consider but for now not touching the addons.

(Would be super cool if anyone else tries this out and reports back though! The compose should hopefully be straight forward and easy to get started with if you are on Linux and have podman available. The report mentions it TL;DR we had to work around the oBO install in LW not properly utilizing the proxy (?) like this and I think same approach could be used to Uninstall Mullvad extension from Mullvad Browser and prevent it from even loading)

Disclaimer: Am konform dev so shouldn’t be a surprise that it’s working well for ourselves I guess. Eager to hear to what extent it’s overfitted for our usage or really as great as I think it is ;)

BTW if you, dear reader, think queries in report of results are cherry-picked in a way that favors it (I don’t think they are but hey, fair), I’m also eagerly accepting input and especially PRs for queries (still have the raw dumps so I can add this quickly) or steps to test procedure (this means I have to rerun all of them so might take longer to update) that could illustrate different tradeoffs and show a more complete picture. Bring it on <3

Daily-driving it now. I think it’s great. If you’re somewhat familiar with the landscape otherwise I think readme explains how it’s different and why. If you don’t mind losing out on some "safety"¹ and latest upstream features² for the sake of a more stable and predictable base, not having reliance on proprietary integrations or even internet, and really removing all non-essential network integrations, then definitely worth a try!

¹: A surprising amount of people think (or at least write online) that a browser that doesn’t block user requests completely aligned with the Google SafeBrowsing blocklists is unsafe and that doing those syncs is an essential feature. If you think this is the only safe default option in 2026 I’m sorry but please consider uBlock Origin. See how opinions on who to trust can affect what “most secure” means. Konform Browser removes many assumptions of trust. But not all; Everyone still comes with an assumed PKI after all and there exists a default for DNS.

²: Since it’s ESR base it means new feature updates from Mozilla ~yearly instead of ~monthly. Still receiving security updates on the rapid schedule. No AI features out of the box.

Thanks! Adding Floorp should be straightforward if you feel like tackling it yourself as it’s “just another FF fork”. Adding a new browser consists of adding a new Containerfile for it. I guess Floorp might be most similar to Mozilla firefox out of the existing ones. PRs much appreciated for new browsers as well as any interesting queries to get more insight into data I can run on existing dumps and add to Report section.

They have official PPA: https://ppa.floorp.app/

For Brave got it running but didn’t yet figure out why it crashes as soon as I try to proceed with the onboarding. Judging by the probably unrelated error noise in the console, it might be trying something weird with a graphics driver or hardware sensor and not gracefully handling not having access to whatever it is 🤷 But didn’t even ldd or strace it properly yet so maybe just a missing library.

There’s a lot that could be done but had to wrap up and publish somewhere.

Do you suddenly need to stop hitting your wife?

LibreWolf is a great project but was killing my eyes at night by not being able to follow dark-theme preferences in Private Mode. So it was forked into what is now Konform Browser. Besides unlocking theming and some other privacy-related tweaks on the preferences pane, it goes even further than LW in disabling built-in remote connections, snoopware, and AI integrations.

If you are a Linux user who haven’t yet found the right Firefox fork for you I hope you will consider it <3

fedi thread

Went low-key public with our internal browser project by sharing here on the feddit. If you’re a dev, packager, Arch Linux user, or already build Firefox from source, this is for you¹. More people using it becomes a shared privacy win. I humbly suggest that this is currently the most privacy-friendly general-purpose GUI browser out there¹.

¹: Others can check back at a later date when perhaps there are more builds running and tested, and more people have looked over the code.

²: Biased? I would never!

It can. Depends on how you use it. Wear gloves and goggles when handling .ml and political memes on .world and such.
