Rated 5 out of 5 stars

I am a very happy user of this addon, thank to this guy.Just one thing is still broken:I have managed three email adresses on thunderbird, with three google calendars as well but after these days, once I open one calendar account, if I try to add a new one (calendar account), it goes to the browser instead opening a new tab.
If you could fix it would be great indeed.
Thanks
