I use Firefox 4.0 and the No Squint extension. If the text zoom is set to 110% the site doesn't work so well. The articles wind up in rendered as a narrow column in the center with a huge amount of left margin. The SSD Decoder tab wraps under Graphic Cards and Motherboards menu line and is unreadable.

I disabled extensions until I stumbled on which one caused the problem. The solution was to reset my defaults to 100% text and 100% for zoom. The old "control +" and "control -" zoom commands did not cause any formatting problems.

I thought I would post this in case anybody else had this problem.
