The "status bar" is unreadable

[SimonSapin]

Thanks for making this! Performance is much better than https://addons.mozilla.org/en-US/firefox/addon/tree-style-tab/ , especially at startup.

When a link is hovered, its URL is shown at the bottom of the window. Without this extension:

This extension changes the style of this bar and makes it unreadable. I had to zoom and look very closely to see that the text was still there at all.

I think the code responsible is after /*** Link Display ***/ in skin/linux/linux.css.

I personally prefer the default style (even if this one was made readable). Maybe this should be a separate extension? This seems unrelated to stacking tabs vertically.
