"Open link in current tab." NOT a bug

[BlackGeorge1817]

All apologies, since this isn't a bug. I looked in both FAQ and wiki but found no information on this.

When changing theme settings in the vimium ui css under options, how does one change, for example, the font-family and box width for the dialog box "Open link in current tab." or "Open link in new tab."? In some themes, the text of this box goes "outside" the Firefox window border and is thus illegible, so I figure if its width is larger or the font is smaller it will all be seen.

Thank you for any answers or advice.
