If you’d like to learn more about Haptic, why it’s being built, what its goals are and how it differs from all the other markdown editors out there, you can read more about it here.
As others have noted, the app doesn’t work on mobile yet. Anybody willing to share the content here for mobile users?
Maybe try it out on standard Firefox as a quick test? While annoying, this would help validate that the issue is with the librewolf changes to standard Firefox.
Also note that I also use both proton mail and drive from librewolf. Even today. If it’s a general issue with this setup, it hasn’t hit my machine (yet)
