Very Good. Rated 5 out of 5 stars
Incredibly useful for bookmarking your place, when reading very long html e-books and the bookmarked place persists across browser sessions.
I would like to see a different type of marking to the rainbow effect used, but knowing just how much work goes into making extensions, I am just grateful that this extension exists at all!
