1797050 - Add `max_manifest_version: 2` to manifest `applications` key

Status: RESOLVED FIXED

(WebExtensions :: General, task, P2)

Description

[William Durand [:willdurand]]

We want to get rid of the manifest applications key eventually and exclusively use browser_specific_settings because applications and bss are kinda interchangeable but not always and it is confusing.

We can "forbid" this key in MV3+ so let's update our schema to reflect that.

Attachment: Bug 1797050 - Part 1 - Use `browser_specific_settings` instead of `applications` in existing `devtools/` tests. r?rpl!

We want to encourage extension developers to use browser_specific_settings instead of applications,
which will be unsupported in Manifest Version 3+. This patch prepares the introduction of a new warning
(that is usually converted into an error in the test environment).

Attachment: Bug 1797050 - Part 7 - Add `max_manifest_version: 2` to manifest `applications` key. r?rpl!

This patch adds the constraint in our schema and fixes the remaining test cases
either by disabling the extensions.webextensions.warnings-as-errors pref OR
by updating the manifests.

Ha, oops, sorry. I think something in the "Part 3" patch is likely needed for the patch I landed earlier.

We have no documentation for the applications manifest key on MDN or the browser compatibility data. If you follow the link to https://developer.mozilla.org/en-US/Add-ons/WebExtensions/manifest.json/applications the page describing the browser_specific_settings key opens. I did find one reference in the notes on contribution to the web extension examples, which I've removed.

Comment 24

[rbloor]

I've also found and fixed several instances on MDN where applications was used as the link text for links to the browser_specific_settings reference page.

Comment 25

[William Durand [:willdurand]]

Then, I guess we are good here?

Comment 26

[rbloor]

Yes - given your feedback that the applications property is still valid in the update manifest, the one remaining reference to this property across our various websites, on Updating your extension, doesn't need changing.
