I really wanted this to work BUT.... I just tried "altering" the icon's description and resaving it back to the desktop. No can do. I edited what more or less said "Seattle Weather, breaking news, Komo" by deleting the Seattle and everything after weather, leaving WEATHER. Three times it saved it with the Seattle still prepended and "weather" cut off since it limits how much shows. Oh, Firefox by the way. I may try Chrome.
Edited to add: Seems to work in Chrome. Although, the icon is more generic as opposed to a nice square with KOMO in its image. The Chrome version on shows a simple "K" Tradeoffs
