The bottom of most of the help pages are obscured by the absolutely positioned orange block at the bottom when Firefox’s Minimum font size feature [1] is used. I currently have a min. font size of 16 set and I can’t see the information at the bottom of these pages.
I also notice text overlap on some pages when the help window is not maximized (in conjunction with my min. font size). For example, the header and the URL on the Bug Reports page (accessed via a link from the "How can I contribute to the development?" page) overlap the right navigation column.
Please redesign the help pages to be more dynamic. They should at least deal with the mentioned absolutely positioned box issue. Specifying CSS overflow: auto/scroll or allowing word wrap would probably fix the second issue.
