The package you downloaded doesn't contain any source code - it's a prebuilt binary. So, you can just extract the files in the tarball (with "tar zxvf firefox-126.96.36.199.tar.gz"), then change to the directory that's created (may be "firefox", or "mozilla" and you use "cd directory") and then run the executable ("./firefox", or "./firefox-bin", I can't remember which).
You have actually created a regular user account for yourself, right? If not, you really should since it's a bad idea to be using the root account all the time.
Edit: and for God's sake, please use better thread titles in future. You are told about this when you post a thread.
