Review for Google Tasks Sync by Ali Vaziri
Rated 3 out of 5 stars
Although the description implies that this add-on is capable of syncing tasks from Google Calendar with Lightning (which is not done by default through lightning), this is not what happens...
As you should know, Google Calendar Tasks and Gmail Tasks are two different animals! This add-on syncs tasks created in Gmail Tasks, but has nothing to do with the tasks created in Google Calendar (the ones you create from the GCalendar web interface or apps in addition to events and goals).
If you are here for calendar tasks, you will be disappointed (just as I was) but if you are using the less known Gmail task lists, this can help you.
To create your own collections, you must have a Mozilla Add-ons account.
