Konform Browser 140.13.0-100 has been released and users are encouraged to upgrade.

https://codeberg.org/konform-browser/source/releases/tag/140.13.0.100

This includes all security fixes from Firefox 140.13.0esr as described in https://www.mozilla.org/en-US/security/advisories/mfsa2026-70/.

Fixes for half of the related CVEs were are included in Konform Browser 140.12.0-104, released last week. Users are still advised to upgrade to latest versions before opening untrusted content. See release notes for details.

Last week also brought in a few improvements and streamlining of settings UI, like making settings related to cross-origin refer(r)ers more complete and understandable.

In other news, Konform Browser sources and build-tooling repositories are now also being mirrored via P2P Radicle Network (@radicle ) for redundancy. If the primary mirror on Codeberg is ever having issues, this more decentralized alternative can hopefully fill in the gaps. Patches and issues can also be submitted via Radicle without need to register account with any particular provider.

All commits on releases are signed with same PGP key and verifying these signatures is encouraged before building from these, especially as Radicle is still relatively experimental.

Konform Browser 140.12.0-103 has been released!

https://codeberg.org/konform-browser/source/releases/tag/140.12.0.103

Some notable news since last week:
- The browser now has a lot more theming options out of the box! This "brings back" the Colorways themes designed by Keely Lascio for Mozilla "Independent Voices" initiative, which were previously part of Firefox for a limited time only. These themes are very lightweight and only affect browser chrome: Negligible impact on installation size and not detectable by webpages. Aesthetics aside, having more builtin color schemes available can be pretty useful for people with multiple browsers/profiles to easily distinguish their domains without having to manually or remotely install new themes to do so. Available at bottom of `about:addons#themes`.

- Fixed multiple media playback issues - certain video or audio formats that would previously play incorrectly or not at all should now play properly.

- Various other smaller fixes and improvements, including some security fixes from upstream. See release notes for details.

In other news, preview release for upcoming v153 is available for anyone interested in testing or browsing on the edge.

Konform Browser 140.7.1.100 has been released. What's new since last week:

- Closed vector of identity leaks and fingerprinting from unique IDs sent in HTTP headers by addons. This is our fix for #mozilla 'wontfix' bug https://bugzilla.mozilla.org/show_bug.cgi?id=1405971.
- #konformbrowser is the only #firefox derivative which protects against this under defaults.
- 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. Reports on if any networked addons break (or not) under different modes much welcome.

- Security hotfix from Firefox ESR 140.7.1

- The new onboarding screen can now show detailed information on exactly what changes each #privacy preset has on #browser settings so you can make educated choice.
- Would love user feedback on if you think any of the presets should be tweaked or anything that's missing
