Bug 1898709 - Use GetMostRecentBrowserWindow() instead of GetMostRecentWindow(u"navigator:browser") to cater for Thunderbird's main window. r=nalexander

Based on https://github.com/Betterbird/thunderbird-patches/blob/main/115/bugs/1863798-toast-notification-foreground-mail-client-m-c.patch

Fixed cases where general code assume main window is Firefox.
GetMostRecentBrowserWindow is getting "navigator:browser" for Firefox, so there is no change in behavior,
but it means more things will work for Thunderbird.
