Icons completely missing!

Hello, recently I noticed the icons are completely missing in Firefox on macOS! They seem to appear in the menus but they're not visible at all. See this image from Instagram:I've turned off uBlock Origin and restarted my browser and it still reproduces. I don't see this issue in Safari.

I'm on macOS 15.7.2 and Firefox 146.0 (aarch64)
