1765316 - Set a default value for the "extensions.manifestV3.enabled" and "extensions.eventPages.enabled" about:config prefs

Status: RESOLVED FIXED

(WebExtensions :: General, task, P1)

Description

[Luca Greco [:rpl] [:luca] [:lgreco]]

The two about:config prefs "extensions.manifestV3.enabled" and "extensions.eventPages.enabled" do not have currently any default value, internally we consider then as set to false when not explicitly set, but at the moment they are not going to be listed explicitly in about:config (until explicitly set by a user).

Extension developers will soon need to use these two prefs to test their add-on on Firefox while preparing their add-ons to transition to manifest_version 3 (and as an intermediary step of that transition, they may want to test their extension as a manifest_version 2 with only the addition of enabling the event pages support).

To make it easier to the extension developers to set these prefs correctly, we want to explicitly set them to false, so that they will be listed in about:config and the extension developers will only need to flip their current value (and avoid to set the wrong preference name by mistake because of a small typo).
