You can rebuild the icon cashe, "If you need to rebuild the Icon cache, Open File Explorer > Folder Options > Views to show Hidden System Files. Next, go to C:\Users\Username\AppData\Local folder and delete the hidden IconCache.db file. Reboot. This action will purge and rebuild the icon cache".
I have checked the file association and it is HTML.
I can change the browser but not the actual icon, before is was a small picture of the contents of the file which my wife noticed had suddenly changed to the Firefox Icon. I did think I had seen how to change the actual icon but I cannot recall how I did it! We, (my wife) have decided to leave it alone, she can open the file ok so it really doesn't matter what the icon is.
Thanks for your help it is much appreciated,
