As suggested by mcs, I tried replacing the Firefox icon with our Tor Browser icon. (When we implement a new Tor Browser icon, we can replace this again.)
and similar files. It seems we need the @2x.png for high resolution displays on macOS unless we resort to .svg files (see comment:5:ticket:27156). However, you are replacing the .svg icons just with .png ones. Thus, I guess that does not take care of those displays and would show the Tor Browser icon blurry.

The PNG file I used is 32x32 whereas the icon in that location is sized to 16x16. So I think these PNGs are effectively @2x already.

Hm, I wonder why Mozilla used two differnt icons for that then if they just could have used a 32x32 one. What speaks against moving to .svg as Mozilla eventually did?

I'm not sure. I guess in principle it's more performant to have the image already at the scale you need. Although it seems unlikely it's a bottleneck.

Nothing, except I couldn't find an SVG version of the green globe icon. If anyone has a copy of it I will be glad to make a new patch using the SVG instead.
