about:preferences privacy pane fails to initialize
When I open "about:preferences" I get the following error:
Uncaught (in promise) TypeError: Preferences.get(...) is null
dataCollectionCheckboxHandler chrome://browser/content/preferences/privacy.js:355
init chrome://browser/content/preferences/privacy.js:1263
init chrome://browser/content/preferences/preferences.js:181
initializeCategories chrome://browser/content/preferences/findInPage.js:109
Most noticeable if you click the "Settings..." button in the security pane, where the broken initiation gives a blank page.
I think it comes from bugzilla bug 1908312, which was backported to ESR 128, and did not wrap the dataCollectionCheckboxHandler in a AppConstants.MOZ_DATA_REPORTING check.
Opened bugzilla bug 1912066. Already reported in bugzilla bug 1910312.
