Why doesn't Cut/Copy/Paste work in Firefox?
The default security settings of Mozilla/Netscape/Firefox browsers do not allow JavaScript code to access your computer's clipboard. Though EditMe's toolbar buttons for Cut/Copy/Paste will not work with these browsers, you can use your browser's built-in Cut/Copy/Paste commands from the Edit menu of the browser. You can also use the keyboard shortcuts:
Cut: Ctrl+X
Copy: Ctrl+C
Paste: Ctrl+V
You can also edit a configuration file to change this security setting for your browser. See this page on the Mozilla site for instructions.
