Question column too narrow in Firefox
The "Top Questions" list contained in <div id="question-mini-list"> has setting overflow to auto. With my Firefox set to have minimum font size to 16 (Options > Content > Fonts & Colors > Advanced > Minimum font size), it makes this list clipped, so almost unreadable. A scroll-bar is added at the bottom of the page, but it's really not convenient. Here's a screen-shot to illustrate the bug:
This bug occurs with any tab of the "Top Questions" list (active, featured, hot, week, month).
More information: if I comment the following CSS property:
#question-mini-list {overflow: auto;}
I don't have the bug.
<hr />toclear: both;.
