Notes

  1. Although the outcome is correct, the browser uses a high resolution PNG icon and scales it down. Depending of the design of the icon, this can lead to poor result. The browser should rather use one of the available 16x16 or 32x32 PNG icons... but it does not.
  2. Apparently, this is due to a recent issue. Firefox behaves the same way with older version of RealFaviconGenerator which used to work.
  3. Not really the "home screen", but the Speed dial
  4. Not the home screen but the Reading List. Here, Safari takes a low resolution icon and zooms it. This leads to a pixelated result.
  5. When adding a bookmark to the home screen, Firefox creates an icon with margins, instead of using the icon in full size. Apparently, there is no way to work around this issue. Even adding mozilla.org to the home screen generates the same result.
  6. When creating a bookmark, the browser uses a default picture (ie. the same for all bookmarks). Apparently, there is no way to work around this issue. It seems that the browser has built-in icons for "famous" sites, but there is no way to specify a particular icon for your own site.
