Rated 3 out of 5 stars
I don't know why anyone enhanced TabScope and TabPreview with the recommended status. At the first view TabPopup works nicely or better. But here too the preview width is limited to about 400 pixels and changes to the preferences requieres a Firefox restart. Seems to be a PreviewDisease. 3 stars.This review is for a previous version of the add-on (1.2.1).
