Question: Safari does not display GMail/Google Reader unread counts in tab titles
1. Create a bookmark for either GMail or Google Reader
2. Click on the bookmark under Safari to load either site (make sure it has at least on unread item)
The text in the tab title will not display the unread count. Instead, it displays either "GMail" or "Google Reader". Firefox displays the unread counts for both sites in the tab's title text as follows: "Gmail - Inbox(2) - <email addr>", "Google Reader (2)".
This is the one of the main reasons why I will continue to use Firefox over Safari. Displaying the unread counts in the tab titles allows me quickly glance at the browser's window with both sites loaded in separate tabs to see if there are any unread items.
