Hello,
Thanks for opening this issue, can you please run the command realpath $(firefox) (or ls -g $(firefox)) and tell me what it shows to you? Also, can you tell me what Linux distribution you're using?

Oops, my bad! I meant to say realpath $(which firefox) and ls -g $(which firefox) (with which). Sorry about that.

Here's what those commands show for me:

What do you see when you run them? Also, which Linux distro are you using? Is it Ubuntu, Debian, Arch, Kali, Fedora, or maybe something else?

@Deslo123 That's super weird. It seems like undetected_geckodriver isn't just missing /usr/lib/firefox, but it can't find the Firefox binary at all. Could it be that you're running the script in some isolated setup that's preventing Python from accessing /usr/bin/ and /usr/lib/? I saw you're using a Python virtual environment, but those usually don't block access like that, so it might be something else.

Let's check a few things. Do you have the /usr/lib/firefox folder on your system? If not, can you see if /usr/bin/firefox is a shell script? Typically, this script runs the Firefox binary found in /usr/lib/firefox, which you can see in my screenshot:

Can you tell me what's inside that file on your setup?

Also, sometimes it might point to another binary in /usr/bin, like on one of my other systems:

If yours looks like this second example, use ls -g on the binary it leads to (mine's firefox-esr, but it could be firefox-developer-edition, firefox-nightly, etc.). For example, the command would look like ls -g $(which firefox-esr) for me, make sure to replace firefox-esr with the binary it points to on your system, after you run this command let me know what it outputs. In my case, it shows lrwxrwxrwx 1 root 30 Oct 9 19:17 /usr/bin/firefox-esr -> ../lib/firefox-esr/firefox-esr.
