The user guide covers every screen and setting.
Troubleshooting explains the error messages and what to try.
Report a problem or ask for a feature
Open an issue on GitHub. Say which version you use (Settings, About and diagnostics), on which system, and what happened.
A diagnostics report helps: in the app, open Settings, About and diagnostics, and choose Export diagnostics… to save it to a file you can attach. Passwords, cookies, tokens, tracker passkeys and keys are removed from it. Read it before you share it.
Security problems
Please don't report a security problem in a public issue. Use GitHub's private vulnerability reporting on the security page.
