Return of the living dead

I've been testing Debian Squeeze beat for a while now, and I'm disappointed to find that a trio of annoying bugs that had appeared in Ubuntu just before I stopped using it are now in Squeeze.

• Copy and paste occasionally fails to work in Firefox (Iceweasel in Squeeze) web forms.
• Trying to safely remove USB hard drive results in a "Unable to stop drive" error message.
• In Movie Player in full screen, the controls disappear when hovered over after the screensaver has been on for a while. (Normal behaviour is obviously for the controls to appear when hovered over.)

These bugs are irritating. They'd be show stoppers if there was any other show in town.

Drat.

Update: two of these bugs (1&3) are actually the same bug in Compiz. See Return of the Living Dead Part II.
