With a browser toolbar or two installed and more than one "tab" open in Firefox, the Block Clipboard does not show up on the screen even when the browser is as big as possible at 1024 x 768 screen resolution.
This is, I believe, still the most common screen resolution on the internet at large.

Reuven, any idea what is causing this? I'm not seeing it on a m.net test site.
