I opened the Github issue linked. For us it represented, at times, thousands of requests per second across multiple users. And that was with affected users getting IP-banned temporarily.
Some of which were 404s which you typically absolutely do not want cached. Or 405s (on HEAD /favicon.ico for example). Or 429s. Or 403s.
Browsers are expected to:
1. Use the favicon specified in meta if any (we do have one, /favicon.svg)
2. Respect cache headers (immutable + multi-months max-age)
3. Not make completely random requests to things they should ignore (such as OpenGraph tags)
Yes CDNs do help with these kinds of issues, but they absolutely do not fix them all. Which is why even though we have a pretty damn elaborate setup in that regard we were being annoyed by the issue.
But also Firefox on iOS should be not-completely-broken.
