Does there exist a firefox.tar.bz2 package for Raspi (!ARM!) which can be downloaded? (Making firefox "portable" on Raspi)

I know there exists a firefox-esr package for Raspberry Pi OS and firefox is also preinstalled on Ubuntu Mint [Raspi-Image].

But in this case I'm trying to get firefox as a .tar.bz2 package from the official release site: https://releases.mozilla.org/pub/firefox/releases/

My goal is, to be able to create a "kinda portable" firefox directory. On my main PC I download the .bz2 package from here: https://releases.mozilla.org/pub/firefox/releases/90.0/linux-x86_64/de/

Then I extract it and can create a script which starts firefox, but saves all of the data in a defined directory!:

#!/bin/sh
"path/to/firefox/firefox" -no-remote -profile "path/to/profilefolder"

But on Raspi I can only run ARM stuff (sorry for this choice of words, I'm not even one year using linux, excuse :/ ) so this formats/packages:

Dir linux-i686/
Dir linux-x86_64/

... won't start on the Raspi :| (I tried the firefox runtime/application in the firefox folder, but it didn't start.

It would mean the world to me, being able to change the profile-data path without taking to deep changes in the OS. So this script workaround is already good- if you have any tips, I would be really happy to hear from you!

I have a tip for you that might work.

You can start firefox like this:

firefox --profile /path/to/profile

Interestingly, you can also just use:

firefox --profile .

Where . tells it to use the current directory as the profile. That way, if it was on a USB drive for example, it would be portable, as long as you launched it that way. All the data would be tied to the current directory where it was launched from.
