## Description

Check the width of currently focused Firefox window every 0.1 second:
<ol><li>If width &lt;= user defined threshold, enable vertical tab</li><li>If width &gt; user defined threshold, disable vertical tab</li></ol>
The user defined threshold is 1080 (in pixels) by default.
You may also choose to reverse this behavior, so that vertical tab is enabled when the window width is ABOVE the threshold (and vice versa).
You can edit these settings in the extension menu.
