Checkboxes dissapear after anywhere between 5-30 seconds, so you have to be fast or refresh the page if they disappear.
So doesn't help much...

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

The extension has a "can't read and change data on this site" error when you try to click on it. Completely grayed out.

Thank you for making this extension.
It was really hard to figure out how to use it. If it wasn't for a previous reviewer, I would've never known to look for delete in the address bar. After I selected the tracks, I didn't see a way to delete. I figured it out after clicking on the menu next to one of the tracks: I coudln't see it before because the option was not visible on my desktop browser.

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. :)
