Jim,

>Michel and I traded some messages on this and I have since destroyed the paper trail :-( However, if you can get Firefox to prompt you about the clipboard access, the trick is to NOT check the remember this decision box, and just click the Allow when it becomes active.

You've to set (about:config)

signed.applets.codebase_principal_support true

I think delay is intentational so prople would read a message before clicking Allow button.

>IAC, anytime I now use the function I get the prompt, and for the convenience it is worth it and should allay any security concerns you might have. Note also that the link you pointed to says this was 'fixed' in the preview release. I am still running the preview release. Works for me?

I just tested in 1.0 and it works the way you describe it.
