The "Browser" button in editor did not work on Firefox 7 :-(
Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIStringBundle.GetStringFromName]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: file:///E:/Downloads/FirefoxBeta/empty/extensions/custombuttons@xsms.org/components/CustomButtonsService.js :: <TOP_LEVEL> :: line 843" data: no]

This review is for a previous version of the add-on (0.0.5.5).
