 Issue 622419  has been merged into this issue.

Unassigning my Harmony bugs pending re-triage of who should own what.

P3 if we decide  bug 726187  is the right way to go (i.e. not adding a URL row to this dialog).  P1 otherwise.

Note from  bug 726187 :

"The hard part of  issue 651652  is that the Combobox dropdown currently only shows toplevel folders. 'Choose another folder' pops the Edit Bookmark dialog to access the full tree of folders.

"Safari shows the full bookmark folder tree in the combobox drop down. It doesn't look too bad. It also omits editing the URL - if you want to do do that you gotta use WebUI."

It looks to me like the mock here makes the URL directly editable, but the folder-tree-in-dropdown thing is probably nontrivial.

Archiving old bugs that haven't been actively assigned in over 180 days.

If you feel this issue should still be addressed, feel free to reopen it or to file a new issue. Thanks!
