In a effort to reduce the size of omni.jar and Firefox footprint, I offer you to replace current bloated images with pixel perfect identical ones that have been optimized using various tools (cryopng, pngout, pngwolf, deflopt and defluff) a lot of CPU cycles and a bit of luck.

File location in source:
mozilla-2.0/other-licenses/branding/firefox/content/about-logo.png

Ends up here:
omni.jar!/chrome/browser/content/branding/about-logo.png

This bug report is a follow-up of Bug 631392

Reproducible: Always

Even smaller file (used current version of pngout and huffmix to reduce size)

The new .png file size is 49502 bytes (6118 bytes smaller than the original - 10% smaller).

As I noted over in bug 631392, I'd rather we find a more general solution to this than tweaking images one by one. (That said, I'm fine with taking this bug since it was already in-flight when the discussion in 631392 happened.)

I just realized that we use this on about:home, since it affects every about:home load.
Looks good to land. I don't see any reason to keep this trivial two-year-old bug open any longer.

The @firefox.exe icon is badly compressed; would shrink 31% if recompressed with Zopfli. (Chrome's shrinks 38 bytes.) pic.twitter.com/PuRXURJKwU
