1364610 - Zombie tabs on Android report an URL of "about:blank"

Status: RESOLVED DUPLICATE of bug 1583281

(WebExtensions :: Android, enhancement, P3)

Technically this might be correct, but it would probably more useful to report the URL and title that would be shown if the tab was actually loaded and instead just set "discarded" to true for that tab.

For the URL we've already got this function (https://dxr.mozilla.org/mozilla-central/rev/8a7d0b15595f9916123848ca906f29c62d4914c9/mobile/android/chrome/content/browser.js#4018). We don't have anything for the title at the moment, but getting it from the session store data would work on the same principle.

The function you mention, how do I actually use it? I tried calling it on a Tab object, and using it like a property on a Tab object, but I can't figure it out.

This may not be the place for this, so if all you do is redirect me somewhere else I'm ok with that.

That's the browser's internal tab object, so from a web extension you don't. That was just meant as a note to whoever wants to fix this, as that implementation is specific to Android.

On GeckoView discarded tabs aren't even appearing in the extension API (bug 1583281), so this bug is kind of "fixed".
I'm however marking it as a duplicate of bug 1583281 so that whoever who works on this feature can be aware of the concern expressed in this bug.
