Review for Attachment Viewer: view in a tab, slideshow by Scuttle@IL
Rated 4 out of 5 stars
Excellent addon. An improvement would be if one click the attachment and have it open with the default app.
Or am I missing that?
What you request is actually the default action which TB offers if you click the filename in the attachment list.
The idea of this addon is to give a quick overview of the document, without having to wait for the default app to open (nor having to close the default app afterwards).
To create your own collections, you must have a Mozilla Add-ons account.
