Announcement Center Icon is not shown using Mozilla Firefox as browser

Mozilla Firefox 60.0.2 for Mac

Safari and Chrome:

Confirmed. In the "disabled apps" settings section, then in the "enabled apps" section, then in ordinary apps "menu" - the icon never shows in Firefox. It shows in Chrome - with both browsers running right next to each other on the same Ubuntu 18.04 desktop.
It also shows in Edge and IE11 on Windows10.

announcementcentre.svg has stuff like:

svg version="1.2" baseProfile="tiny" width="11.29mm" height="11.29mm" viewBox="0 0 1129 1129"

but other app.svg have:

svg xmlns="http://www.w3.org/2000/svg" height="32" width="32" version="1.1" viewBox="0 0 32 32"

I will guess that the different height, width, version, viewbox is causing it not to render on Firefox.

"Since becoming a recommendation in 2003, the most recent "full" SVG version is 1.1. It builds on top of SVG 1.0, but adds more modularization to ease implementation. The second edition of SVG 1.1 became a Recommendation in 2011. "Full" SVG 1.2 was meant to be the next major release of SVG. It was dropped for the upcoming SVG 2.0, which is under heavy development right now and follows a similar approach to CSS 3 in that it splits components in several loosely coupled specifications."

So I suspect that Firefox does not support SVG 1.2

Other posts give the impression that you are "just lucky" id SVG 1.2 works in any browser:
