I’m kinda confused.

1. Some apps are open source, why not just send a PR?

2. Most apps are actively developed, why not just send a report?

I’d understand this 20 years ago when updates weren’t frequent, or if software was rarely updated. But patching Firefox in your OS feels completely unnecessary.

That’s weird. Didn’t Chrome plan to freeze that already years ago? Did they walk back?

This is it.

Let’s say you’re covering a red pixel with a black pixel. There’s no way that red pixel will in any way “survive JPEG compression” because the compression happens on the raw pixel data; the raw pixel data no longer has a red pixel.

I don’t think what you’re saying makes sense. If you covered all information, no information is left. The blocks are irrelevant since 100% of the information is gone. There’s no “history leak” in JPEG, which is basically what’s being asked.

The only issue I see is meta tags and embedded thumbnails, which some cameras do. Stripping EXIF is always required.
