Firefox for Web DevelopersThe CloseWatcher API landed in Firefox 149, making it easy to listen for platform-specific 'dismiss' signals. Here's how it works:
And, of course, the full documentation on MDN https://developer.mozilla.org/en-US/docs/Web/API/CloseWatcher
Axel Leroy@firefoxwebdevs Something I noticed in the example is that if the browser does not support CloseWatcher, the "Close" button does not work.
I get that the button's event listener calls watcher.close() for demonstration purposes, but I feel that in production it would be more appropriate to call closeSidebar() instead, maybe the accompanying text should reflect that?

@firefoxwebdevs Also of note: on Firefox for Android Beta 149.0b10, the "Close" button works, but it does not intercept the back gesture, returning to the previous page instead. Chrome behaves as expected.
@axeleroy I'll look into this. Thanks!
@axeleroy yep, I can recreate this issue, but looks like it's fixed in Nightly.
