It can happen, that all mouse input is ignored (keyboard appears to remain working).

Reproducible: Always

3. immediatelly click and hold (drag) "(download it)" in the same line of text. (just drag it a bit and wait a second or two)

Actual Results:  
While dragging , the "Software Installation dialog appears, but is blocked. No buttons or widgets can be clicked. If I start a new window of Firefox from the Quick Launch bar, its winows also has the mouse blocked. Keyboard input seems to work.

I was able to reproduce. BTW: I was able to press the escape key to close the xpinstall dialog and resume normal operations. The Extension Manager code isn't involved until after install is clicked in the xpinstall dialog... not sure if this is a widget, core xpinstall, or toolkit xpinstall (e.g. XUL and JavaScript that drives the dialog) bug.
