Addons-frontend: Warn AMO users when visiting the site with Fenix

[bobsilverberg]

From the PRD at https://docs.google.com/document/d/1HOImPu2RO9PXIbrNvE_YhYyONw7n-rgjzMtMQ3Knk4Q/edit.

When a user visits AMO using Fenix, a warning should be displayed similar to the platform warning implemented via #8701. An an add-on detail page, the warning will appear below the install button, similar to the current warning:

The text for this warning will be "This add-on is not compatible with Firefox for Android. Learn More."

On all other pages, the warning will appear at the top of the page, similar to the current warning:

The text for this warning will be "To learn about add-ons compatible with Firefox for Android, click here."

In each case there will be a link to either a SUMO article or a collection of add-ons that are compatible with Fenix. That is TBD.

@jvillalobos The SUMO article that we'll be using as the link destination, at least for now, has been published at https://support.mozilla.org/kb/add-compatibility-firefox-preview/. This article discusses our plans for add-on compatibility for Fenix, but doesn't present a list of extensions that are compatible. I am therefore wondering whether the text we're using in the warning makes sense, as it's not particularly accurate.

We're currently proposing using:

"This add-on is not compatible with Firefox for Android. Browse compatible add-ons."

and

"To find add-ons compatible with Firefox for Android, click here."

but the information in the linked article neither allows users to "Browse compatible add-ons" nor to "find add-ons compatible with Firefox for Android".

Do you think we should change the text of the warnings for the initial implementation and update it later if we do have a link which helps people find compatible add-ons?

[jvillalobos]

How about
"This add-on is not compatible with Firefox for Android. Learn More."
and
"To learn about add-ons compatible with Firefox for Android, click here."

We will update the article once we have more information on Fenix compatibility. We can also change the messaging on AMO then.

I verified this issue on dev with FF Preview 71.0.1(Android 9.0) on a mobile device and also changing the UA in the FF72 browser (win10).

• the red warning message from https://github.com/mozilla/addons-frontend/issues/9069 which was available on top of an add-on detail page has been replaced with the yellow warning below the disabled install button. The "Learn more link" opens the specified SUMO page in the same tab.

I believe (but not 100% sure) that the red warning message is no longer wanted together with the new yellow warning - on the detail pages. Let me know if it's ok this way.

• the new yellow warning on the rest of the pages is available too. The click here link will redirect to the same SUMO page.

Yes, the red warning about Fenix compatibility on an add-on detail page should no longer be seen.
