There are some parallels between LibreOffice and Thunderbird that make The Documentation Foundation&#x27;s adoption of Thunderbird attractive.<p>1. Both LibreOffice and Thunderbird are desktop implementations of applications for which most of the recent momentum has been behind web-based implementations (Google docs, GMail, Office 365, etc.). So TDF is used to the desktop vs. web dynamic.<p>2. Both LibreOffice and Thunderbird has large installations in business&#x2F;government environments.<p>3. Both LibreOffice and Thunderbird started out being governed by different organizations and would be adopted by TDF (slightly different situation for LibreOffice which was a fork, though Thunderbird will be forking off its shared base with Firefox). So TDF is used to adopting legacy code and continuing to evolve it.<p>That said, I hope the TDF scrutinizes Thunderbird and only takes it on if it is confident that Thunderbird fits into its overall mission and infrastructure. In recent times I have liked what I have seen from TDF and been somewhat disappointed by Mozilla, so I wouldn&#x27;t Thunderbird to hamper LibreOffice&#x27;s momentum.
