Has somebody tried compile Firefox 7 (last officially supported for N810/N900) to Maemo Leste?

Here you can find source:
https://ftp.mozilla.org/pub/mobile/releases/7.0.1/

Is this the last nightly source (Fennec 10) Maemo 5?:
https://ftp.mozilla.org/pub/mobile/n...ra-maemo5-gtk/

It might enough light weight browser to N900 and
it would be nice if that Maemo UI integration code can used with Firefox 102 with Pinephone or Droid4.
