I open Firefox and the open window is blank (as it should be, because I have set my Preferences to open firefox with a blank window. Then I select a Bookmarked website from my Bookmarks Toolbar, which opens then opens that website in the window fine. BUT, the Address Bar remain blank. It does not display the URL of the web page that has been opened from the Bookmark. Why not? Firefox always did this in the past, but this problem has existed since the last few updates, and still does now on the latest v22.0 for MAC. If I open another blank TAB, then switch back to the first tab, the URL of the first tab does appear. But what a pain. I shouldn't have to open another tab, then switch back to the first tab, just for the URL to appear in the address bar. I can't believe this problem has existed for so long now over at least 2 or more version upgrades. Please fix.
