Note, to someone looking deeper at that issue: this is visible only if one starts with the slider set to the safest setting. Changing it later does not do anything with respect to this bug (which is interesting). This is both reproducible with 8.0.8 and 8.5a10 on my Linux box and thus not related to our security settings redesign in #25658.

I think it might be related, I was testing an addon called Simple mass downloader: https://addons.mozilla.org/en-US/firefox/addon/simple-mass-downloader/

Its buttons show up fine under Standard or Safer security levels and becomes invisible under Safest security setting. Feel free to open another issue for this if you think it's unrelated.

Screenshot attached. The one on the right is for safest security level.

On safest security level, video/audio controls like play/pause, full screen and volume disappear as well.

That's a symptom of when svg is disabled. I looked at OPs attachments last night and my first thoughts were glyphs/icon-fonts/tofu, call it what you will or maybe ligatures ... or svg
