Firefox missing icons.

Not sure of the best terminology to describe the issue so here's a picture to explain.

Left: Firefox Right: Chromium

For some reason certain icon's do not display on Firefox. It's just annoying really. Is there a fix for this problem?

Off the top of my head could be a problem with the cache, javascript, or plugins. Try clearing the cache and then disabling your addons to see if it corrects the problem otherwise maybe

sudo apt-get update && sudo apt-get upgrade

might help.

One possible cause of missing icons:

I used DOM Inspector and I see:

etc

My suspicion is that OP has some overzealous ad blocker or stylesheet.

Thanks for the help. The adblock idea reminded my that I had a user agent add on running. Once I turned it off all was resolved.

Interesting that modifying the UA string was responsible. (I know that "mobile" pages can be different than "desktop" pages.)
