Finally with Firefox 26+ Download StatusBar couldn't keep up with Mozillas updates and faded away.
Last update of DSB from 2011 is old and weak and does it's last job in Ff 25 - with higher Firefoxes it works in no way.
I'm sure that there is no more update to be expectable as the owner of DSB has changed in 2011 from Devon Jensen to C.J. who obviously just adopted this (his only) add-on - and as a side note, does not one solely review about other add-ons!
It's too bad about a formerly well made (by Devon Jensen) and valuable add-on.
When I read "Download Statusbar 2 is in development and will be made available soon" I really tried to push myself to trust in a new version coming.
But... 3 years no more update since the former add-on owner has been leaved, except the attempt with an unfortunate "sponsorship mechanism"-version! It's very hard to believe in a new version coming, and well, I've hoped 2013 brings a new DSB to us ... NOTHING !!
What a SHAME !
