My Firefox icon looks exactly like it always has in the past.
Mine didn't. My KDE4 icon theme was an offshoot of oxygen. And apparently, they updated it with this kewties anime (sp?) look.
To everyone thus far: I have tried every right click option in the panel on it imaginable and been unable to change it in the panel. I have had similar hard time editing any icon in the panel. But this is the only one I can't live with.
I had some weird success making shortcut to the app firefox (no %u) in home folder and then dragging it to the panel, I get the option to edit the icon then. Not sure why the %u makes the icon uneditable? When I try to create a link in the panel that has %u I get you have to be root. Maybe I should try editing the icon for this app in root?
In the meantime, managed to totally destroy the panel and have been rebuilding - rather proud of self. If I didn't have so much invested in my KDE4 config would have just reinstalled the pkg like the old days. But am patiently rebuilding.
Right now, changed to a different Oxygen branch that doesn't have this ridiculous icon for firefox. *sorry, too lazy to try and get to my web host to post a shot of the ridiculous icon, trust me, it is cartoony, anime style and just, not fitting with my theme
