Can I see if someone uses snapshots to store parts of my website as images in their laptop, using browser snapshot tool?

    As opposed to with any other screenshot tool? Why the focus on Firefox snapshots? Dec 15, 2022 at 14:39

    I usually use a screenshot tool that doesn't run in the browser at all. I like the ones where I can draw a box on the screen and it creates an image from that. Dec 15, 2022 at 15:10

    Why would you care?

    Any images that your web site displays will be available in the browser cache, where the user can retrieve them.

    Android applications can set a "do not allow screenshots" flag, mostly seen in banking apps. I personally find that annoying and there are ways around it, but writing a thin app wrapper with this flag might be enough to fulfill your requeriment.

No, as there is no API for detecting screenshots. It's impossible to arbitrarily know what happens outside the browser as that would be a security issue.

You can track the clicks on the keys like PrtSc with JS

    Wouldn't this particular key be handled by the operating system, so the browser was not even informed of it? Dec 18, 2022 at 18:39
