I’m using the Tab Mix Plus Firefox Extension for one simple purpose mainly. I don’t like the way Firefox handles if you open more sites in tabs than the width of your screen can display. The default way is that Firefox makes the tab list scrollable which is not a perfect solution. I was looking for an extension that would create an additional row and place all the new tabs in that row. Tab Mix Plus supports this feature, you can select the maximum number of rows that should be added, the default value is three rows which means that two additional rows will be added if necessary.
