Review for ReminderFox by Hoggy
Rated 5 out of 5 stars
There's another Google calendar for web extensions, but it doesn't even come close to how nice THIS addon has been for many years.. Plus that other one feels almost like tease-ware.
In any case, thank you so much for creating this addon.. And I hope you're able to port it over.
