When trying to update my website, after installing Firefox 4.0.1 I was unable in import new photos or cut/paste within the 'admin' section of my Zenphotos website mono-art.com.au I followed your link to: https://developer.mozilla.org/en/Midas/Security_preferences There was no "user.js" file in Firefox/profiles, so I created one and added your recommend codes: user_pref("capability.policy.policynames", "allowclipboard"); user_pref("capability.policy.allowclipboard.sites", " http://www.mono-art.com.au/ "); user_pref("capability.policy.allowclipboard.Clipboard.cutcopy", "allAccess"); I still can't import photos or cut/paste. What do I do now??? You didn't say Firefox 4.0.1 is only a Betta version. Would it be best to return to my previous version? I need to update my web site and this is a real problem for me. user_pref("capability.policy.allowclipboard.Clipboard.paste", "allAccess");
