Hi, I dealt with this problem several time and I decided to write down my solution to save of others time. In case you install firefox on Windows 7 and your htm, html files are showing blank white icon instead of little foxxy one, all you need to do to go for registry as below: - I am using Firefox v.84, ues problem is there since firefox v.2 - - Type regedit and go for "HKEY_CLASSES_ROOT\FirefoxHTML-308046B0AF4A39CB\DefaultIcon", perhabs you see a differentt number beside FirefoxHTML or even no number - - Double click on Default key and change the value to "C:\Program Files\Mozilla Firefox\firefox.exe,1", not to mention without "" - Don't forget to backup whole your registry before editing it - Restart and you will probably see the Firefox icon on your saved html files

Good luck
