It's been a while!

Konform Browser version 140.12.0-100 was recently released and if you aren't aware it's time to upgrade! ^1^

Konform Browser is a free/libre and open-source (FLOSS) fork of Firefox ESR with the primary goals of security, privacy, and user freedom. Shows by example how these three goals don’t have to be at odds but support each other and work in harmony. Runs lean and light with lights off out of the box, while making it convenient to toggle on the features you want. All telemetry removed, none added. Fingerprinting and tracking extras with base defaults on par with (or exceeding) Tor Browser, still keeping common-sense tweaks like dark mode and installation of self-built addons available without making a fuss about it. Graceful degradation for private networks and more granular control for those who want a browser that really conforms.

"ESR" means there's a major upgrade coming up soon with the expected jump from Firefox ESR version 140 to 153 next month. Work has already been ongoing for a while to prepare Konform Browser v153 to be the most secure Firefox build at release. Early alpha builds based on FF153beta are available for anyone who wants to do early testing or help out with any other contribution.

Current Konform Browser 140.x is production-ready and expected to keep receiving security updates and bugfixes for at least a couple of release cycles after initial v153 release so users can upgrade at their leisure.

If you try it, would love to hear your feedback on the browser - and if you like it, tell your friends!

Release notes

Would like to share this FLOSS project been working on for a while now and hope that is cool with you all!

Was not satisfied with status quo on browser options for our use-cases and needs - hence Konform Browser evolved.

Whether accessing private resources and actually wanting to keep that private, or minimizing traces left when surfing online, Konform Browser makes that easier with uncompromising hardened defaults combined with extended configuration UI and features like built-in container tabs for additional isolation and more flexible proxy configuration.

Binaries only provided for Linux but sources should be buildable for other platforms.

Looking forward to hear thoughts and feedback on project!

Keeping up with security updates for your web browser is of increasing practical relevance. Under normal conditions this means important updates roughly every couple of weeks.

Mainline firefox or chromium packages are typically easy mode: For most people it's a matter of staying on top of regular pacman updates. torbrowser-launcher updates from inside the browser and is also usually painless to manage.

Running custom builds or forks from AUR requires more attention. Is the AUR package up to date? If it's a fork: Are security updates from Mozilla/Google downstreamed in a timely manner? Have you built it? Can you still build it? How long since you pulled and rebuilt that ungoogled-chromium binary and how many CVEs has it racked up by now?

Anyone running firefox-esr or any derivative like icecat, waterfox^1^, mullvad-browser or konform-browser from AUR should probably be paying attention to this right now:

Arch Linux repositories updated llvm and clang to v22 on 2026-03-07. This caused a regression for Firefox ESR packaging resulting in compilation failure when building.

Firefox ESR 14.9.0 was released on 2026-03-24.

This means that since then, users of the AUR packages for these browsers have not been able to build a new version with security fixes on up to date Arch Linux system. Some users may be prepared to handle this by maintaining separate build infra with internal registry where keeping system packages frozen on older version is acceptable but for everyone else, this is a conundrum.

Anyone browsing the web on firefox-esr or a derivative should make sure you get fixes for the issues addressed in 140.9.0 asap.

konform-browser AUR package has been patched with clang 22 toolchain fixes from mozilla and should now build succesfully. The other forks including firefox-esr will still need manual patching or downgrading clang toolchain packages to v21 to compile. The konform-browser patches for clang 22 are in the AUR repo and should be portable to the other browsers too. If others can share their results in testing (both X11 and Wayland) or reviewing the fix, this might help in sorting out the firefox-esr situation sooner than later, too.

^1^: Looking at git log it claims to build as of the wasi-compiler-rt21 makedepends but I have still not been able to make it compile when attempting. Please LMK if I'm holding it wrong and there is a way!

Announcement brought to you by Konform Browser

I would like to invite all of you Linux users to check out the latest release of Konform Browser.

Konform Browser is a free/libre and open-source (FLOSS) fork of Firefox with the primary goals of security, privacy, and user freedom. Hoping to be an example of how these three goals don’t have to be at odds but support each other and work in harmony. Would love to hear your feedback on if it's in the right direction and what can be improved.

Been posting on and off the lemmies about the project during 2026 and previously on this community. Below are major highlights since 140.8.0-103 update from two weeks back:

• Bundling and enforcing use of bundled fonts. Konform Browser now carries the same font-loading patches and bundled fonts as Tor Browser and Mullvad Browser. While this does increase download- and installation sizes, it has two clear benefits: - Significantly improved resistance against font fingerprinting used by tracking scripts. Konform Browser should now be more robust against this attack by having shared global font fingerprint. - All languages and scripts should render as expected regardless of what fonts you have installed on system.
• Also bundled is now Multi-Account Containers Lite addon. It's a debloated^1^ fork of Firefox Multi-Account Containers so you can utilize Container Tabs and set per-container proxies without installing addon for it.
• While "AI chatbot" feature was already disabled and hidden by default, it was previously still possible to trigger activation of proprietary networked centralized cloudbots by setting pref browser.ml.chat.enabled=true. These have now been fully removed and replaced by a single provider utilizing locally running llamafile instance.
• Ported a bunch of security fixes and improvement on fingerprinting protection from FF Rapid Release and Tor Browser which didn't make it into upstream FF ESR.

For details and references see linked release notes. For even more details I hope the commit log is digestible.

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: @[email protected]^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.

Set up a framework to fully man-in-the-middle my own browsers' networking and see what they're up to beyond just looking at their DNS queries and encrypted tcp packets. We force the browser to trust our mitmproxy cacert so we can peek inside cleartext traffic and made it conveniently reproducible and extensible.

It has containers for official Firefox, its Debian version, and some other FF derivatives that market a focus on privacy or security. Might add a few more of those or do the chromium family later - if you read the thing and want more then please let us know what you want to see under the lens in a future update!

Tests were run against a basic protocol for each of them and results are aggregated at the end of the post.

Posting with ambition that this can trigger some follow-ups sharing derived or similar things. Maybe someone could make a viral blog post by doing some deeper tests and making their results digestible ;)

Good time-of-day, Linux users! I hope you will take kindly^1^ to coming here to tell you about Konform Browser and what it is. And also ask you to try it out in case this is your cup of tea :)

In short, Konform Browser is a web browser with the goal of promoting user freedom and access to the rights of security, privacy and anonymity. It is intended as a general-purpose browser fit both for daily online surfing as well as targeted deployments in secure or untrusted environments. It is fundamentally a patched build and custom configuration of Mozilla FireFox ESR. It started as a fork of LibreWolf and now stands on its own four feet.

Some highlights to give an idea to those familiar with LibreWolf or other FF fork:

• Security: Konform is based on Firefox ESR instead of Rapid Release. This means a more stable base without missing out on the latest security updates, in exchange for longer time waiting for the newest features from Firefox. It also enables shorter lead times to backport upstream updates.
  • In this sense (and a few others), Konform Browser is closer to IceCat/GNUZilla than it is to Librewolf.
• Freedom: Konform allows a higher level of customization. It gives the user control and trusts you with that responsibility. Some examples:
  • Allows enabling dark mode and following system theming even when Resist Fingerprinting is enabled
  • Allows installing your own self-built unsigned add-ons
  • "Spoof referer source" user configuration option
• Privacy and security: Disables all browser features relying on external network connections.
  • "RemoteSettings" is completely disabled^2^.
  • No cloud "AI" integrations. You can run Konform on a disconnected network and not notice any reduced functionality.
  • All telemetry, metrics, and ads from the browser disabled.
  • OCSP turned off (but we have CRLite).
  • tcpdump and see the difference!

I should add that even if we contrast with LibreWolf above, this is not at all meant as a dig or criticism. I think they have done and continue to do great contributions for the benefit of all of us. That we chose it as upstream and that it's the easiest to compare with is a testament both to how closely aligned we are and that Konform has a lot to thank Librewolf and the wider Firefox customization community for. Like they built from Librefox and Arkenfox to bring private browsing to a wider audience, so are we but the next to try help widen and deepen the browser ecosystem.

The recommended installation method is building from source but there are also binary packages for x86_64 and arm64 built by Codeberg CI. Currently Linux only, considering Android next and could use some assistance with that.

Doors open for users, testers and contributors. Looking forward to hear what you think and if there's anything missing!

^1^: Disclosure: Am dev. This is a rewritten crosspost.

^2^: This means that local full-page translation is also unavailable even if in principle it should be possible to bundle and run translations fully locally. It's just the way Mozilla built it. Patches towards allowing users to enable fully offline translations would be very welcome.

There is a new Firefox fork in town: Konform Browser. Its focus is privacy, security and user freedom. Yes, I know this sounds familiar - but hear me out, I do think we have something to bring to the table!
