Description

https://github.com/filips123/PWAsForFirefox/blob/main/extension/src/images/page-action-install.svg uses black fill.

Firefox used to auto-invert this, but that caused other issues, see https://bugzilla.mozilla.org/show_bug.cgi?id=2001318

Nowadays, it's easy to make an svg that supports both light and dark mode, see mozilla/multi-account-containers#2835 for an example (note that change still hasn't been released).
