google office copy paste problem

firefox prevents the sites to copy or paste malicious contents, so this security feature also blocks normal functionality of google office. Below mentioned fix can be extended to add exceptions for another sites too. 

step 1 : open user.js file in mozilla profiles dir.
$> vim ~/.mozilla/firefox/<profile dir>/user.js

step 2 : append following lines in the file.

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

step 3: save the file and restart the firefox.
