Hello. I changed the firefox icon with resource hacker and if I open it from the firefox folder everything is fine, but when I pin it to the taskbar and open it, it turns back to the original icon and stays like this. I tried this already, no success. https://support.mozilla.org/de/questions/844131#answer-270774

Can anyone help me? I really want a custom icon to go along with the rest of my theme, but it seems the firefox doesn't want this :P

I'm running Windows 7 x64

Do NOT use resource hacker to change your icon because it might make firefox unstable. Instead, use this :

  • Unzip omni.ja in your Firefox application directory.
  • Delete omni.ja or rename it (e.g. omni.ja.off).
  • Create directories icons/default in the Firefox chrome application directory.
  • Copy the icon file you want to chrome/icons/default/main-window.ico
  • Start Firefox and enjoy your new icon
