troubles between Yahoo Mail and the app tab
I cannot use the app tab as I do with Chromium because, when I click on the link Mail in Yahoo's Home Page, Firefox opens a new tab instead of using the same app tab. So, it is completely useless. Is there a way to let Firefox understand that I want the Yahoo webmail in that app tab and not the Home Page?

I have this problem with Basecamp and Writeboards also. Very frustrating.
Opening a Writeboard is not a problem, because Basecamp does a redirect to the corresponding Writeboard URL. But clicking "Back to Basecamp" from a Writeboard is a direct link, with a different top-level domain... so Firefox opens it as a new tab.
This should probably be a per-app tab option to stay within the same tab or open different URLs in a separate tab.
