Allow Copy and Paste in Mozilla Firefox

 

 There are other methods but I found the addons outdated. This is one method I would recommend.

Novice Users:

Note: This method could be prone to user error. You may want to try the next one where you install a plugin, do a copy/paste, and then edit a value.

• 1) Create a new window or tab.
• 2) type 'about:config' into your url bar. (No quotes.)
• 3) Now right click in the content section of the browser, and select New->String.
• 4) Enter 'capability.policy.policynames' into the "New String Value" box. (Without quotes.)
• 5) Click OK
• 6) Type 'allowclipboard' in the "Enter string value" box. (Without quotes.)
• 7) Click OK

Repeat steps 4-7 with the following string name/value pairs:

NOTE!: Replace both www.mysite.com values with your domain name. Do not include an ending slash on the website, or copy/paste will not work. Also note that you can add multiple sites using spaces.

Name	Value
capability.policy.policynames	allowclipboard
capability.policy.allowclipboard.sites	http://www.mysite.com https://www.mysite.com
capability.policy.allowclipboard.Clipboard.cutcopy	allAccess
capability.policy.allowclipboard.Clipboard.paste	allAccess

You may want to bookmark this page in case you need to come back.
Now exit all Firefox/Mozilla browser windows. You should now be all set to use copy/paste. Restart....

• Note: Kupu still lets you use ctrl-X for cut, ctrl-c for copy and ctrl-v for paste.
