how to build firefox in pi5 yocto image

[gitgonewithwind]

Hi all,
sorry to bother you again.
before I used chromium-x11 in pi5 image. my docker build ENV works well.
for some reasons, I want to build firefox.
but after I added meta-browser/meta-firefox in bblayers.conf
and added (or not added ) fIMAGE_INSTALL_append = " firefox" in local.cong to build
there is an error output:
ERROR: The following required tools (as specified by HOSTTOOLS) appear to be unavailable in PATH, please install them in order to proceed:
python python2.7

I added python 2.7 in Dockerfile (default python3 I think) , but it was output:
ERROR: The following required tools (as specified by HOSTTOOLS) appear to be unavailable in PATH, please install them in order to proceed:
python

I did not how to add python ？？？？？ I added python in Dockerfile, but can not find the source

I use it commit 1879cb8 (HEAD -> master, origin/master, origin/HEAD)

I found the first error output:

it looks like use wrong compiler C version?
how to fix ?
any idea?
Thanks

Take a look at https://github.com/OldManYellsAtCloud/meta-browser if you haven't already found it

Original meta-browser repo hasn't updated Firefox in 4 years. Not sure on compatibility with RPI 5 though
