I'm running Firefox Nightly 50.0a1 on OS X El Capitan version 10.11.5. This problem startted 2016-06-08 build. 2016-06-07 build has no issues.

Just for reference; when I open "chrome://browser/content/browser.xul" and click Bookmarks menu of the browser.xul window, Nightly shows the icons correctly.

Is this bug duplicate of bug bug 1272067?

Sorry for typo. Is this bug duplicate of bug bug 1279099?

I don't think that is a duplicate of bug 1279099.

After landing Bug 1280006 - Backout "Bug 1270680 on mozilla-inbound, firefox/tinderbox-builds/mozilla-inbound-macosx64/ seems to fix this issue. So I think this bug is a duplicate of Bug 1279099.

Hi Jonathan, I saw that you worked on Bug 1279099, do you think this bug is a duplicate of Bug 1279099 ?
