Compatibility - Clicking WebMail Notifier does not open in Unloaded Tab

[qwerty017]

When clicking on the Webmail Notifier Icon and the tab for, as an example, GReader is loaded then it will just reload that tab as it should. If the tab is currently unloaded though it will create an entirely new tab, almost as if it doesn't notice that there is currently a tab already on the tab bar.

same for this bug - it needs a yellow label.
