I really enjoy the look of UBUNTU. The only thing that I want to change is the default icon used for .html (.htm) files. I want to use the icon /usr/lib/firefox/browser/icons/mozicon128.png instead. I do not want to change any other visual element. Is there a practical way to accomplish this small change?
edit: @Mitch, I've used assogiate in the past and although I was able to change the icon used for .mht files, I could not get it to change the .htm icon.
@Anwar Shah, thanks for the information. I wish that it would work for me. Running 13.10 x86, after I do the copy of the icons, in the folders are a bunch of links to .svg files not actual graphics files. It appear that the second copy actually went into /usr/share/icons/Humanity/mimes/... and replaced the links there with the renamed .png files. I hope that nothing too weird happens as a result. I have rebooted a couple of times and nothing seems amiss, but no Firefox icons for the .htm files yet either.
