Notes

  1. For some reasons, some browsers use several pictures: they pick one or the other for no particular reason. For example, Safari on iOS 5.1.1 uses the 57x57 and 114x114 Apple touch icons.
  2. When adding a bookmark to the home screen, Opera Mini uses a default picture (ie. the same for all bookmarks). Apparently, there is no way to work around this issue. Even adding opera.com to the desktop generates the same result.
  3. When adding a bookmark to the home screen, the builtin browser of the Samsung Galaxy S uses the 16x16 PNG picture. It is not clear whether this is an issue of RealFaviconGenerator or just the normal behavior of the browser. In addition, the HTC Desire, which is a similar device, behaves correctly.
  4. When adding a shortcut to the desktop, Firefox creates a default icon, which is not user friendly. Apparently, there is no way to work around this issue. Even adding mozilla.org to the desktop generates the same result.
  5. When adding a shortcut to the desktop, Firefox creates an icon with huge 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 desktop generates the same result.
  6. Speed dial.
  7. Add its own padding to the home screen icon.
  8. When adding a bookmark to the home screen, Samsung Galaxy S5's default browser uses a default picture (ie. the same for all home screen bookmarks). Apparently, there is no way to work around this issue. Even adding samsung.com to the desktop generates the same result.
  9. When creating a bookmark, UC Browser uses a default picture (ie. the same for all bookmarks). Apparently, there is no way to work around this issue. It seems that UC Browser has built-in icons for "famous" sites, but there is no way to specify a particular icon for your own site.
