Scope of this bug is to validate if setting `browser.startup.homepage_override.mstone` pref is enough to not show about:welcome during first startup. By default `browser.startup.homepage_override.mstone` isn't set for brand new profiles but there has been issue reported for custom builds when about:welcome page isn't shown due to `mstone` pref set https://mozilla.slack.com/archives/C90HG2UQH/p1710940398696639 https://searchfox.org/mozilla-central/rev/b73676a106c1655030bb876fd5e0a6825aee6044/browser/components/BrowserContentHandler.sys.mjs#221
