I'm experiencing the very same issue (modal dialog stating that cut/copy/paste is "Currently not supported by your browser, use keyboard shortcuts instead."). This is occurring in FF 3.0.10 from two different machines and also from a brand new clean install of FF 3.5 Beta 4. I tested all against http://tinymce.moxiecode.com/examples/full.php and although CTRL X/C/V keyboard commands all work, neither the cut/copy/paste icons nor the contextmenu plugin dialog will work without prompting the error dialog window.
Yes, I have the user.js set up properly and working in all instances and browser has been restarted to be certain it has taken effect:
user_pref("capability.policy.policynames", "allowclipboard");
user_pref("capability.policy.allowclipboard.sites", "http: https:");
user_pref("capability.policy.allowclipboard.Clipboard.cutcopy", "allAccess");
user_pref("capability.policy.allowclipboard.Clipboard.paste", "allAccess");
As a matter of fact, using the very same machine/browser I am able to cut/copy/paste against a TinyMCE 3.1.0.1 installation, no problem -- I can cut/copy/paste using the icons in the toolbar, the contextmenu and CTRL-X/C/V without any issue.
I've been trying to troubleshoot the issue but have come up empty so far.

The closest I have traced it back so far was line 12850 near the only instance of "queryCommandSupported" in the src.
