We have a LocationBar class that appears to be unused cruft. I need to verify that it's not used in some obscure way in a nib, then remove it from the tree.
Oops, forgot all about this. Removed on trunk and MOZILLA_1_8_BRANCH (and removed from the project on branch, where I apparently forgot during the great project upgrade).
(Why I thought there was no bug while I was writing the checkin comment, despite having been reminded about doing the removal by this bug, I can't imagine.)
