I have never seen an Opus file in the wild. MP3 and FLAC are by far still dominant. Ogg is still popular I. It’s niche (eg game sounds, and I think Spotify uses it too)

On the website? Can browsers natively play them?
Yes, it's one of youtube's standard audio formats.

Yes.
Opus is great. I encode all my music in Opus for playback (after buying it in FLAC). Are all browsers supporting it now? I remember in the past Apple staunchly refused to support Opus and Ogg container. Is it better now after they joined Alliance for Open Media?

ALAC (Apple Lossless) was specifically designed to be power efficient, hence its use in AirPlay. Interestingly one of the most power efficient lossy codecs is still ATRAC, Sony's MiniDisc codec, specifically designed to sip lightly at your AA batteries.
Doesn't seem to be the case at least in Rockbox, ATRAC is less efficient than Vorbis or MP3: https://www.rockbox.org/wiki/CodecPerformanceComparison

All major browsers now implement WebRTC, including Opus support. Also, most browsers now support Opus playback in HTML5, though AFAIK Safari only supports it in the CAF container. See https://caniuse.com/#search=opus
Apple being Apple. While they "support" it, looks like they can't even do it properly.

Is there a reason why mp3 is still around? AAC has better compression ratios, and support is a non-issue. Maybe mp3 has better brand recognition? Most people know what a mp3 is, but probably wouldn't know what AAC or a .m4a is.
The only point in lossy encoding is to save space / bandwidth . Opus excels at getting good sound quality at lower bitrates. If there's a talk or lecture on Youtube that you're about to grab, try the 50kbps Opus version and save your limited space for more important things, but you might need to remux from webm to an ogg container for compatibility. e.g. youtube-dl -f249 $URL --exec 'ffmpeg -i {} -vn -c:a copy {}.ogg…
For example, an hour-long performance video mp4 at 1280x720 gets you 96k audio and 280MB. 'youtube-dl -f 251 url' will get you a 160K Opus in 54 MB.
To my ears Opus sounds sweeter and fuller than mp3. At 64K and lower bit-rates, it's near the top.
