Firefox's dotted focus outlines on links disappear Rated 4 out of 5 stars

I use FireGestures 1.6.4 in Firefox 4.0.1. Assuming there are two tabs named A and B separately, and there is a link named C in A.

When I use FireGestures to close B ("close tab" gesture: up) opened by middle-clicking C and then switch back to A, the dotted focus outline on C disappears.

If I close B using non-gesture methods (e.g. clicking Firefox built-in close button), the dotted focus outline on C will remain appear.

I tried the extension "Mouse Gestures Redox 3.1 pre". It didn't produce this problem, but FireGestures has more built-in gestures I need.

Please fix this "dotted focus outline disappears" problem, thanks.

This review is for a previous version of the add-on (1.6.4).
