A good fix of a failed change Rated 5 out of 5 stars

Indispensable add-on for those who use Firefox as a working tool. It is very difficult to work with a black background, because the bad shows boundaries of dark images and transparent GIFs. It is unclear why Mozilla does these awkward changes. Thanks to the authors add to the fact that they retain this browser most convenient.

This review is for a previous version of the add-on (1.0).
