maybe sandbox is blocking her what's the browser ?

Here is an example how I would automate opening the default web browser with multiple tabs, each tab containing a different URL that was read in via a list.

for i in $(cat list.txt ); do
     firefox -new-tab https://$i &
     sleep 1

This is fixed now. With kali-themes 2021.4
You need to remove /root/.config after updating too, to remove previous settings

This does not fix the issue.

root@kali:~# firefox-esr
Running Firefox as root in a regular user's session is not supported. ($XAUTHORITY is /home/kali/.Xauthority which is owned by kali.)

Hello again.
Sorry, I didn't explain it properly as I thought this issue was not about running the command firefox as root but about opening links from a root program. In any case both are solved as explained below

The issue with firefox can't be "directly" fixed. Firefox does not allow running it as root if your session is run by a regular user, that has been like that for a while. That's why in old versions of kali you could open firefox as root, because you were using the root user for the whole session, not only firefox.

Now the solution:
What you need to do is open firefox as the user owner of the $XAUTHORITY file:

root@kali:/# USER=$(find $XAUTHORITY -printf '%u')
root@kali:/# runuser -u $USER -- x-www-browser

Now, this is already fixed with the update of kali, as we've added this script to a new helper app called 'Default Browser' and now it is configured as the default browser for all desktops. This way, no matter if you are running a program as root or as a regular user, when you click/open a link from the app, this helper app will ensure the browser (in this case firefox) is run as the current logged user.
So now with this fix, a simpler way to open a link from the terminal would be:
root@kali:/# xdg-open

To make this update work you need kali-themes 2021.3 (sudo apt update && sudo apt install kali-themes)

This change has caused another issue.
While running as root, you are now unable to to open a local .htm file using these methods:

1. xdg-open index.htm
2. Paste the following into an open browser: file:///root/index.htm
2. From an open browser > ctrl + O > Filesystem > root > Open
          Could not read the content as root.
          Error opening directory '/root/': Permission denied

If you are not running as root, why are you using everything as root?
You can't access root's files with a regular user, that is normal. You can change the permissions of the files so that your user's browser can open them. Or just, move to the root user for everything.
