Rated 3 out of 5 stars

I installed this program expecting it to lock up my firefox like it does on my other computers, and I wasn't disappointed. I have several google calendars with years of reoccurring appointments, some of them shared with others, and as soon as the add-on synchronizes with my google account, firefox starts to lag. The next time I start firefox, within about 5 seconds, the entire program locks up and gets into a wonderful and gratifying loop of asking for my password and telling me that there is an unresponsive script. This happens on both windows and linux, so when I decided to move to another computer, I said to my self, "Self, you should install that google calendar sync add-on into this computer so you don't have to look at your calendar or read any email!". Great job guys, keep up the good work! I wanted to use my phone for the calendar app in the first place, who needs a desktop anyway?

This review is for a previous version of the add-on (1.0.4).
