Hi all!

Latest version of Konform Browser just dropped and now I come here to share with y'all about what's been cooking.

If you are new to Konform Browser, dev writing and previously posted on on this community introducing the project here.

Highlights since last time:

  • Latest security fixes from up to most recent Firefox ESR 140.7.1.
  • A new welcome screen (pictured) where user can quickly choose between how private vs integrated experience they want, from a locked down "Purely Private" all the way to an unleashed "Just Make It Work" (affectionately referred to as "yolo mode")
    • The "Show detailed information" link leads to a table showing exactly what settings will be impacted by each preset so user can make educated decision and understand impact before choosing.
  • Improvements around privacy and fingerprinting. In particular: Closed a significant vector of identity leaks and fingerprinting from unique IDs sent in Origin headers of HTTP requests by addons. This is a previously known issue (1405971) that has been considered wontfix by upstream for 6 years now.
    • To my knowledge, Konform Browser is the only Firefox derivative which protects against this under defaults and improves over status quo in chromium too. Attempts are being made to reach out and see if the patch can also be of interest and benefit for Tor Browser.
    • New user pref network.http.addonOriginBehavior can be tweaked to further change behavior and work around any breaking addons.
    • A future update might change default to 3 (random), which could make browser choice less fingerprintable. The current default is not set in stone and I'd be very curious about what breaks and what doesn't if anyone plays around with this.
  • Now also publishing binary packages for easy installation and updates from Alpine Linux and Arch Linux package repos, alongside deb/rpm ones. All builds and releases are produced by Codeberg CI. Building from source is of course still supported.
  • Various improvements and fixes for optional features unlocked by "Just Make It Work" preset

There is also now a more official fedi account on Mastodon where an abbreviated version of this post is already shared with a couple of screenshots of the new onboarding: @konform@techhub.social^1^.

As always, installation and build instructions can be found from release notes and doors are open on Codeberg for issue reports and merge requests alike.

^1^: Still figuring out how crossposting works or doesn't across the fedis! In case federation clients botcher the link: https://techhub.social/@konform

When i have problems in Wayland, Report it at Codeberg?

Yes! And thanks for trying :)

As you do, it will help to know if you also tried Firefox (or other derivative) and if results there are same or different from Konform.

When someone willing to package and test that shows up ;^^

In particular, being on flathub means someone with a github account needs to push it up (sorry i'm done there).

Here is a starting point: https://codeberg.org/konform-browser/flatpak

Happy to iterate on codeberg with anyone who wants to tackle this
