All my icons are nice-looking, thanks to the elementary os theme. however, firefox icon is the default icon and not changed.
I have installed ElementaryPlus theme to add additional icons but firefox was not included.
Anyone have tried changing firefox icon? is there a way to change it?

OS: Elementery OS Loki 0.4.1

You can edit the default firefox.desktop file:

First open terminal and copy the original one:

cp /usr/share/applications/firefox.desktop ~/.local/share/applications/

Now edit the copy ~/.local/share/applications/firefox.desktop with your favorite editor.

You need to adjust the line containing




Mostly icons are stored under /usr/share/icons/... Probably you will find your desired icon there.

  • I also found a theme called Elementary-Add on Github which has a firefox elementary-styled icon. I copied the 48px sized icon and added it to ElementaryPlus theme folder. Then, turn off and on ElementaryConfigurator+ ... and it worked..! Commented Jun 6, 2018 at 18:05
