It works! I get a mile long list of unwanted scrobbles from YouTube and stuff, when I forget to disable scrobbling. This works to clear them out. You do have to remember that a trash can icon appears in the address bar and click that, and not the extension icon. Thanx for this!

brings critical functionality to last.fm. works great. thank you!

suddenly i got strange2000+ scrobbles on the iPhone app so i needed to delete them and found this. i tried firefox and even chrome ver. but i got "please log in" error when im even logged in on both browsers like said below. it's beyond hardest to delete each 2000 so fixing this would be so much help. thank you.

Edit:Dev fixed after 11 hours i posted this. working perfectly now. great add-on!

Everything worked smoothly, but I guess after some lfm update today I keep getting "You are not logged in. Please log in to use Last.FM Unscrobbler." message even though I am logged in. Reboot didn't help, so I can only assume it's bc of new labs feature that appeared in my profile

Finally find one that actually works, thank you.

Works perfectly!
At first, I didn't see the icon for activating the checkboxes, but after mailing the developer, I got a quick reply explaining to me to look in the address bar. I should of course have seen it there, I can only blame my eyes. :)
