We have a couple of PNGs/GIFs: https://dxr.mozilla.org/mozilla-central/search?q=ext%3Apng+ext%3Agif+-path%3Aimage%2F+-path%3Aaccessible%2F+-path%3Atest%2F+-path%3Atests%2F+-path%3Amozscreenshots%2F+-path%3Abuild%2F+-path%3Aeditor%2F+-path%3Adevtools%2Fdocs%2F+-path%3Agfx%2F+-path%3Ajs%2Fsrc%2F+-path%3Amobile%2F&redirect=false A lot of them can be replaced by photon SVG equivalents (https://design.firefox.com/icons), or a lot of them can simply be removed.

Hi Richard, The bugs here have been removing some PNGs, and I've just realized that some of them *might* be used by comm-central. Could you check if the changes here haven't broken anything on your side ?

Thank you for the heads up, Tim. I CCd me on the bugs which affect TB.

I suspect the jumplist's icons on Windows (new tab, new window, new private windows) are still PNGs. Would be nice to have them updated to Photon's ones.

They're actually ICOs: https://searchfox.org/mozilla-central/search?q=&case=false&regexp=false&path=browser%2Fbranding%2F*%2F*.ico I suspect it will be difficult to use SVG here.
