Uses 150MB of RAM...rather intensive.

Doesn't work on youtube music

Sadly all functionality is gone and this extension seems abandoned. The Last.fm site recommends using the extension called "Web Scrobble."

functionality has been very hit or miss recently, it only scrobbles once or twice a day for some reason. I disabled other youtube extensions i had installed to see if that was the issue but its still not working

works after playing 1-2 songs on youtube... Devs, please keep the manual short, particularly the part how to activate/connect (!) the scrobbler-addon with your lst.fm account!..

just doesn't work

This doesn't work well in mixes, which is . . .inconvient

Works well but it really needs a manual scrobble mode where you have to click a button in order to scrob

Does work with the latest edition of Firefox. However, beware that when adding to your scrobbles it DOES NOT scrobble which album your are scrobbling from. Only artist and track. Sadly, editing scrobbles is only for Pro users on Last.fm. Otherwise the plugin works as intended.

This add-on is pretty well-designed but just DOESN'T SCROBBLE.

Scrobbles some non-music videos at random, whether or not they are in a set category.
An option to NOT scrobble something, like a little X beside the heart, would be good.

Doesn't work if the song/artist isn't already listed in a database, which is pretty dumb.

Working Perfect !
