Revealed: Our Plans For Thunderbird On Android

Best wishes,

PS: I will happily stick with FairEmail


I hope they will truly create Thunderbird for Android. Meaning also calendar and contact sync via DAVs. It would make Nextcloud more integrated with the same apps as on my desktop. Next up is a Mozilla launcher with focus on performance and privacy? Integrate Pocked as the Google Feed and boom! That would be a great strategy for Mozilla as a comeback. I think in large part they lost popularity because they were slow at developing mobile apps. Firefox on Android has only become doable since about 2 years?


K-9 will eventually become Thunderbird for Android

For me it’s read as fact, not as eventually :wink: in official blog post
Let’s see what the future brings
Can be to the advantage and become great, but can also completely miss and fall into oblivion. Then 12 years would be pure memory…

That would be great news if they can pull it off!
My main fear is that they don’t actually have the resources to do it well (enough).

As a long time K-9 Mail user, this is great news :tada:
I have a recurring donation set up, but the main dev joining the Thunderbird team and getting a stable working environment with secure funding can only mean good things.
And if it stays exactly the same I’m happy too :smirk:

I did support FairEmail in the past as well, but K-9 Mail ultimately feels more at home for me. To each their own I guess :slightly_smiling_face:

You can sync calendar and contact sync already via DAVs if you install the DAVx app, https://www.davx5.com/. I don’t use Nextcloud, but run Radicale on my server, and have used the DAVx app to sent up calendar and contact sync on my Fairphone 2. Should work the same from Nextcloud.

I know, but it doesn’t really look like a well integrated solution to me. I prefer Thunderbird for such an integration. But I suppose they will just rename K9 to Thunderbird.
