Know the Risks First
Thunderbird Daily is for development.
Thunderbird Daily is not intended for general use. As a precaution, assume it will be unstable and result in data loss. We recommend you join the Daily forum to keep up to date with any news.
Take Precautions
- Prioritize frequent, thorough backups of your daily profile.
- Expect very frequent, disruptive updates and install strictly to a daily-specific directory.
- Limit mail filters to a single daily profile, or preferably, avoid them.
- Assume most add-ons won’t work.
- Avoid using POP accounts with daily. If necessary, configure to leave messages on the server indefinitely.
