It is the best, the one that should be, it is the one that I have always been looking for.

Thanks

перестало работать как следует. broken, hided from mail panel.

For the people saying it no longer works, there's a new option to open in a New Tab - this has to be selected. It's the only way it works now.

Gyors működés.

Was a great addon until the last update of Firefox - now it does not work, infinite loading on the popup window ._.

Funciona bien. Es mejor que abra una nueva pestaña.

It stopped working on Firefox after the last update.
Перестало работать после последнего обновления

Funciona, és útil i el seguiré fent servir.

No longer works

Great addon! Saves time. Google should make same application for windows shell.
