Clipboard access problems in Firefox 17ESR
I just installed Firefox 17 ESR. Before I was on 18 (latest). I noticed that the hack I put in my profile prefs.js and user.js to allow clipboard paste,cut and copy operations no longer works. I tried clipboard helper add-on it is not working either. So, I created a new profile, put the following text in user.js and prefs.js
user_pref("capability.policy.policynames", "allowclipboard"); user_pref("capability.policy.allowclipboard.sites", "http://mydomain"); user_pref("capability.policy.allowclipboard.Clipboard.cutcopy", "allAccess");
anything changed/different in 17ESR and Firefox 18 ?

Hmmm, even if you are permitting clipboard access through the capability mechanism, starting in Firefox 17, sites can no longer use the old privilege elevation request system. I believe they need to upgrade the scripts (by signing them with a digital signature) in order to manipulate the clipboard.
Is this critical for your application? In other words, can you get by with the standard Windows methods for cut/copy/paste:
Ctrl+x / Ctrl+c / Ctrl+v
