normally pretty good Rated 4 out of 5 stars

This is one of my default extension to add to FF. Much better than native option. Also highly configurable.

However, I'm pretty sure I've found a bug (hence the 4 stars).

No means of contacting author (that I've found), even on new homepage.

Also, "donate" and hosting info is incorrect / needs updating in the About section of add-on.
