Rated 3 out of 5 stars

Works. But only if you have the patience to not convert too many files at once. Plus it annoyingly will first download the file in its original format and then convert it in the background in a manner that slows the computer down noticeably (yes, perhaps there is no other way, but it annoys me, still).

This review is for a previous version of the add-on (3.2.3.1-signed.1-signed).
