AFAIR the GL support is added by the driver via alternatives. I don't recall
how I fixed this few years ago on one PC with NVidia, but you can have a
look into update-alternatives. I read the manuals some time ago to setup
custom firefox installation and it looked like this.

update-alternatives --install /etc/alternatives/firefox
x-www-browser /opt/custom/firefox/firefox 300
update-alternatives --set x-www-browser /opt/custom/firefox/firefox

It could be more work though as you have more symlinks for NVidia for sure.

I think the proper way would be to purge/remove the package with its
configuration and setup again or new one properly.
