I think this is one of the best addons out there and i love the simplicity of it, however i keep getting an error from time to time that makes Firefox un-useable Says "A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue. Script: moz-extension://8916be42-727f-…/data/content_script/inject.js:94"
