Works really slow, and takes forever to load.

Sadly it doesn't have the same performance as the normal Notifier

It takes ages to load, from 5 to 8 seconds, no button to open Gmail in a new tab... Disappointed.

It used to be one of the best add-on for Gmail.

But the recent version doesn't run properlly.
Just "Syncronizing ....".

rotating, since 0.2.6 and nothing more. Have to downgrade up to 0.2.5 witch works fast and smooth
