It works great, very useful addon for me and it works without any problems. And also there is no ads. So I'm too happy with this addon. Thanks a lot.

Excelente, Rapido

Useful! Thank you so much

Thank you so much for the last Firefox update !! We know this addon was working for a long time only if we used the "Add account and keep login status" and it required extra permission to use gmail account.

Now it's working perfectly just as the same as in Chrome without needing to add the account manually, I returned to FF again just because of this :)

Only problem I noticed:

The move To Folder function not working currently.

Im getting "error: Error getting labels backup method" error.

GREAT!!!!

Yes, very good

stopped working (feb-2018)
documentation directs to chrome version
