maybe updating firefox may help?

• Update Firefox to the latest release

I have this problem too. I created a word document and attempt to copy and paste it into Todo Institute blog discussion board, it states that Mozilla does not allow me to do so and to contact Firefox to release the restrictions. I've reset Firefox several times, problem remains. How to fix this? Any helps is appreciated.

Do you get this error using a paste button in the site's editor? Firefox limits access to the clipboard for privacy reasons (because if scripts can read the clipboard when you click a button, what's going to stop them from doing it any time they like?).

Do any of the standard methods for pasting work on the site:

• Ctrl+v (or on Mac: Command+v)
• right-click > Paste
• Edit menu > Paste

Thank You. The direction is too complicated for me to follow. Also others have reported that downloading the add-on caused Firefox to crash.

Sorry. I tried your suggestion - didn't work. :-(

I have Windows XP. I downloaded FF for Windows XP. Overall the system works BUT the problem with Mozilla-Firefox copy/cut/past remains unresolved.

Did you try to use the keyboard instead?

Use keyboard shortcuts if the buttons on the web page or other methods aren't working.

• Copy: Ctrl+C or Ctrl+Insert (Mac: Command + C)
• Paste: Ctrl+V or Shift+Insert (Mac: Command + V)
• Cut: Ctrl+X or Shift+Delete (Mac: Command + X)

Yes, using keyboard shortcuts for copy/cut/paste worked. Thank You. But why can't FF do it automatically like it used to do? How can this function be restored in FF? Appreciate a response and direction to restore this function. :-)

You can try to create a user.js file and add the lines to set the capability.policy prefs to it.

• [/questions/936323]

Enter the URL of the site to the capability.policy.allowclipboard.sites pref, separate multiple sites with a space character.

• user_pref("capability.policy.policynames", "allowclipboard");
• user_pref("capability.policy.allowclipboard.sites", "http://");
• user_pref("capability.policy.allowclipboard.Clipboard.cutcopy", "allAccess");
• user_pref("capability.policy.allowclipboard.Clipboard.paste", "allAccess");

You can test with this code in the Browser (Firefox/Tools > Web Developer;Ctrl+Shift+J) if it will work

var {classes:Cc,interfaces:Ci} = Components;
var PS = Cc["@mozilla.org/embedcomp/prompt-service;1"].getService(Ci.nsIPromptService);
var PB = Cc["@mozilla.org/preferences-service;1"].getService(Ci.nsIPrefService).getBranch("capability.policy.");
var obj = new Object, txt = "Granting Clipboard Access"; 
try{obj.value = PB.getCharPref("allowclipboard.sites");} catch(e){obj.value = "";}
if (PS.prompt(null,txt,"Enter website(s) to allow access to the clipboard\nUse a Space character as separator",obj,null,{})){
PB.setCharPref("policynames", "allowclipboard");
PB.setCharPref("allowclipboard.Clipboard.cutcopy", "allAccess");
PB.setCharPref("allowclipboard.Clipboard.paste", "allAccess");
PB.setCharPref("allowclipboard.sites", obj.value);
}

Hi cor-el. Appreciate the instructions. Unfortunately, I'm not computer literate enough to attempt corrections in the software. Also, other comments about similar problems indicates that this method does not really work. So, I don't want to risk messing up my computer and be tied up with FF problems indefinitely. Sorry. But thank you for helping me. :-)

All you would have to do is to create a user.js file in the Firefox profile folder and paste the above posted lines in this file and complete the site URL to the domain (address) of your school website.

user_pref("capability.policy.policynames", "allowclipboard");
user_pref("capability.policy.allowclipboard.sites", "http://< append site url >");
user_pref("capability.policy.allowclipboard.Clipboard.cutcopy", "allAccess");
user_pref("capability.policy.allowclipboard.Clipboard.paste", "allAccess");

You can use this button to go to the Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

Be sure to use a plain text editor (e.g. Notepad on Windows platform) and choose to display all files when saving this user.js file (Save as...).
If text files is selected then Windows will add a hidden .txt file extension and you get a user.js.txt file that won't work.
