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.
