Great add-on Rated 4 out of 5 stars

This is great - just what I needed! If I have so many tabs open that there are scrollbars in the tab bar, this add-on fixes the problem where opening a link creates a new tab all the way at the beginning of the tab bar. The only problems I have are that the context menu and zoom controls don't work in the popup version of the app tab and opening the popup doesn't clear the app tab (the "glowing" color change indicating that something changed in the app tab is still visible).
