image copy fails under Firefox

[npjg]

When I'm running the extension under Firefox, copying a compiled PNG fails with this error logged in the console: document.execCommand(‘cut’/‘copy’) was denied because it was not called from inside a short running user-generated event handler. Is this a known issue? Or has Firefox policy changed since summer development?

We never had a problem with Firefox during summer development. I just used Firefox with v0.6 and did not see an issue. I am assuming this is 0.7 specific then.

The permissions issue should be fixed by a recent commit, but #5 might be a bug caused by the clipboardWrite permission in the manifest.
