Last.fm Manual Scrobbler

works perfectly, does its job.

Works just fine. Much better than extensions that automatically detect song data, ruining your library.

Works as described. Avoids issues with other extensions that would automatically detect artist/track titles and prevent me from modifying them.

Compared to other scrobbler extensions that either don't work or don't support some websites I use, it's kinda pathetic that I have to resort to entering text for scrobbles. But hey, this extension works just fine.
