Using it (the main app i mean) with regular license from year. It's the best in this field and value all the money. Update frequently of the main app ... i remove one star only for this addon because i'm waiting from 2 years that you add a way to customize the shortcut ... in some languages the default shortcut are already in use by firefox itself ... i'm unable to use the ALT-SHIFT-C for example. Please add the way to customize the shortcut and you gain the last star ! :)
