I can recommend the "NoSquint" Firefox add-on that remembers your preferred text size for each site: https://addons.mozilla.org/en-US/firefox/addon/nosquint/ https://addons.mozilla.org/en-US/firefox/addon/nosquint/ My pet peeve on layout is when a page is multi-column, but each column is taller than the viewing window, so the reader must scroll or page down in each column, then go up for the next column, then down to the next page. This issue often shows up in PDF versions of scientific journal papers. Bonus points if a "page down" function operates on the source page images rather than on the window view (iow, if repeated "page down" only shows the top of each source page, rather than each visible part of the viewing window.) Mouse-wheel scrolling helps, modulo interface "features".
