Firefox popup blocker blocks ctrl-V from Google Reader

Found the solution on Google Groups (Google Reader Help):

1. In a Firefox window, enter "about:config" in the address bar.
2. In the "Filter" field, type "popup_maximum".
3. One preference, called "popup_maximum" appears; double-click the
"value" number.
4. Enter a new, appropriately large value. I used 2000, just to be on
the safe side.
