Great! Rated 5 out of 5 stars

Great Add-on! Definitely should be the default pdf reader. Finally I get a unified interface for zooming, searching. One enhancement though: "Download" should be replaced with "Save", since file is already downloaded; the file should be saved from the cache. Hope new enhancements are added in the near future.

This review is for a previous version of the add-on (0.3.175).
