Test Firefox extension with Android (Fennec)

[Rob--W]

I haven't tested the Firefox add-on with Android. There are no real technical objections to explicitly support Firefox on Android. Most work is in improving the UI/UX of the viewer for small touchscreen devices.

Tried it on Android FF v49 and when you go to download it you get an error saying the extension appears to be corrupt. I tried downloading a couple other versions and got the same thing, hope this helps.

Thanks for testing. WebExtensions on mobile is still in early development at Firefox, so this is not a complete surprise.

The online version at https://robwu.nl/crxviewer/ seems to work, meanwhile (the UI needs some more love though).

[berlamont]

Yeah the WebExtensions can be hit or miss on mobile.
I've been using the Aurora channel for a week or so on mobile and the extension installs just fine on that. So it's something about the current stable channel that probably will be fixed here at some point.

Now it works pretty on Firefox for Android, tested with v59.0.1.

This bug seems fixed in 56.0.

Well, not really "fixed". Although usable, the UI is not really optimized for mobile (small) (touch) screens .

[KrasnayaPloshchad]

OK, I agree with you. I suggest using respontive web design to reconstruct the UI.

And you need to add additional attribute in there:
<meta name="viewport" content="width=device-width, initial-scale=1.0">

Adding meta viewport does not magically solve the problem that the current UI is not designed to fit on small screens. I sometimes use crxviewer on mobile if I want to view the source of an extension, and while it works, it is not very user-friendly. To properly support mobile screens, I would need to redesign the user interface, and I currently don't have time for that.
