Rated 4 out of 5 stars
I have to upgrade my previous review. As I stated before, this is one of the best add ons for Firefox but previous review was negative due to constant Nag screen. If you download a lot it really helps seeing what are you doing.
Nag screen (donate, donate) has stopped appearing! This ad on is back to all my PCs.
4 stars due to lack of support from the developer. Not one of my e-mail was answered. I suggested option to control line spacing between lines so you can have them tighter - no answer. I figured out myself; you have to go into prefs.js and search for >user_pref("downbar.style.db_progressIndicator< and play with the numbers there.
