Hi beehaw friends! Long time no C^1^!

Konform Browser version 140.12.0-100 was recently released and if you aren't aware it's time to upgrade! ^2^

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!

If you're talking about Librewolf's "resist fingerprinting":

  1. That is done for a very good reason (unfortunately, it's not Librewolf's fault that most websites are assholes and have found ways to uniquely identify every individual on every system)
  2. You can very, very easily turn it off per-site, or browser-wide, or it has many configuration options in-between if it really bothers you that much.

If you’re talking about Librewolf’s “resist fingerprinting”:

To set the record straight, ResistFingerprinting was originally developed by Tor Browser developers, and is for some time now part Firefox (and therefore all forks) behind the privacy.resistFingerprinting ("RFP") preference. So credit there goes to those devs, Tor Projectt, ad Mozilla. Konform Browser and Tor Browser have this on by default. There is also the related more recent and complex privacy.fingerprintingProtection ("FPP") system. LibreWolf has historically been on RFP too - I'm not up to date if that's still the case or if they've migrated over to FPP yet as I understand that is the intention of maintainers. The difference between the two is more than I bear to explain here and a bit of a rabbit hole x)

Going into about:config shouldn't be needed for such a major aspect as a "feature" that messes up the timing of scheduling messages. Why is this not in the official settings page? I'm not saying time zone-scrambling is inherently bad to do, even if it's opt-out, but nowhere is anything said about it even existing during the installation or first-use process, and it's nowhere to be found in the browser's settings page without having to rummage in about:config. That, I greatly disliked enough to return to Waterfox (and have also branched out to Floorp, but I digress).

You do not need to rummage in about:config, there is literally a checkbox for it in settings. Maybe this was not the case when you tried it, I don't know.
