Article: Firefox Fix For The Copy-Paste Problem
 Here is how to fix the copy-paste problem with Firefox.  If you have this problem you already know what I'm talking about.  If you are not sure if you have this problem try to highlight text in Firefox, then try to copy it.  If you get an error, then you have this problem.

Here is how you fix this:
First thing, you need to make sure that you have hidden files and folders unhidden.  To do this:
Click Start, then My Computer.   Click on Tools then Folder Options.  
 



 
On the View tab check mark Show Hidden Files and Folders , and uncheck Hide Extensions For Known File Types then Click Apply
 



 
Now, click Start then My Computer then navigate to
C:Documents and Settings{YOUR USERNAME}Application DataMozillaFirefoxProfiles   
   
 In that folder you should see a folder with letters for it's name.  Mine was named, dwu187zl.default although yours may be something different.  Open this folder.



 
  In this folder you should find a file named user.js  Right-Click   on this file and click "Open With", then "Choose Program..."
 



 
Then from the list of programs, select WordPad
 
 


Click Ok, and you should see something similar to this (if it's blank don't worry)



 
Then Add the following to the bottom of this file:
user_pref("capability.policy.default.Clipboard.cutcopy", "allAccess");
user_pref("capability.policy.default.Clipboard.paste", "allAccess");
like this:



 
Then click Save. Then Reboot.  Problem Solved.
 [Note: upgrading to Firefox v1.5 also fixes this problem]
