Strange Firefox icon on dock. How to revert to usual one?
Hi,
The Firefox icon on my dock has changed to a strange one. How to revert to usual one?
I've already discarded this one into the bin, and dragged the normal icon from the Applications folder into the dock. Every time this weird icon is inserted instead of the official Firefox one. I don't get it...
See a screenshot of the current strange one.
Thanks for your help!
