Used the add on helper for clipboard and it did not resolve my issue with the problem that I cannot use clipboard with emails.
Attempt to compose an email using my company email program webmail.windstreamhosting.com. I cannot in the email cut, paste, or copy.
When I attempt to use an option to cut, paste, or copy I receive an error message. "Copy/Cut/Paste is not available in Mozilla and Firefox. Do you want more information about this issue?"
I am then redirected to the website: https://developer.mozilla.org/en/Midas/Security_preferences
I followed the suggestions and it did not correct the problem.
