The Firefox logo requirements: "PNG and JPG supported. Icons will be resized to 128x128 pixels if larger." It seems that they're normally square (or provide their own whitespace).

Please check

@Prtksxna This work has become higher priority because T234386 is dependent on this work. Thanks!

This is what I had in mind for the icon and promo image:

Here is the zip with the PNG files and retina versions:

This looks good. Thanks!

The other graphical element we need for the browser stores (required for Chrome; optional for Firefox) is a screenshot. Any preference for which wiki, article, revision, etc. to use?

Logo PR: https://github.com/wikimedia/WhoWroteThat/pull/60 (already merged, while I was writing this).

Refs:

• Firefox: https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/icons
• Chrome: https://developer.chrome.com/extensions/manifest/icons

Thanks @Samwilson! Should we also add https://developer.chrome.com/webstore/images#promo?

Oh yes! Oops, I knew that. :) I got confused because it seemed to conflict on Firefox. I'll make a new PR.

I've uploaded the above files to https://commons.wikimedia.org/wiki/Category:WhoWroteThat so I can use them on translatewiki.net. @Prtksxna I guess you've got original SVGs too, that could be uploaded there?

No, I was right before: the promo doesn't go in manifest.json (or in the repo), it's a manual upload to the extension's profile at https://chrome.google.com/webstore/developer/dashboard

Oh, I see. I didn't realize this either, thanks for checking 👍🏽
