recently my firefox icon at the kde status bar become a broken paper with a "!" in middle. Not the orange colored global.
anybody know it is why?

Disclaimer: I don't use KDE.
However, I think that this error could be caused by the icon for firefox not being in the location that KDE expects. Perpahps you upgraded Firefox and the icon changed location or it could simply be that Firefox didn't add the icon at the expected place.I would try to find the path that KDE is looking for the icon or and put the icon there or change where KDE is looking to the correct place. Sadly, I don't know how to do this.
Good Luck.

Hi DixieLand,
I have solved the problem. I found there is old firefox residue file Firefox.desktop in my ~/.local/share/applications.

I unmerge my current firefox first then delete Firefox.desktop, then reinstall firefox again. This problem gone.
