1930828 - Cannot change RemoteSettingsExperimentLoader collection after startup

Status: NEW

(Firefox :: Nimbus Desktop Client, defect, P3)

Description

[Beth Rennie [:beth] (she/her)]

The RemoteSettingsExperimentLoader lets you specify the collection it should fetch recipes from via the messaging-system.rsexperimentloader.collection_id pref. However, this has never let you change the collection without restarting the browser because the remote settings client is defined using ChromeUtils.defineLazyGetter (previous version before prefFlips: here, this was not a regression), which replaces the getter with the result of the callback after the first call.

Instead, this should be a regular lazy getter that returns RemoteSettings(collection). We do not have to worry about the collection being garbage collected because it is kept alive by remote-settings.sys.mjs
