Auch nach dem letzten Update auf SeaMonkey 49.1 funktioniert der Provider für Google Calendar wunderbar. Hiermit hat Philipp eine großartigen Beitrag für Mozilla geleistet. Ich halte meine Google-Kalender hiermit auf allen Systemen (Windows, Linux; zuhause, am Arbeitsplatz) synchron. Auch mobile Änderungen von Android aus werden unmittelbar in Lightning übernommen. Ich werde gerne noch einmal spenden!

This review is for a previous version of the add-on (3.3).

Works as expected with Lightning 3.1b1 and Gdata Provider 0.31pre.

Yesterday I tried Gdata Provider 1.pre-tasks-v5 for the first time - works as well. Organizing multiple task lists is a little bit cumbersome (each list as a separate Lightning calendar), but can be done at least. The UI isn't really suitable for managing several lists. Some kind of drop down list selection would be nice, just as offered by the Google Tasks Sync plugin.

You should make sure to use the corresponding and compatible versions of Lightning and Gdata Provider. As I'm working with SeaMonkey (latest version 2.26 works fine with Lightning 3.1b1, Gdata Provider 0.30pre, and German language pack) I cannot tell you with versions you need. Could be helpful to look into the support forum:
