Does system-wide jupyter (apt-get install jupyter) package work for
your Firefox?
If it doesn't, then the problem has little to do with Sage.
(and probably you'd need to fiddle with your Firefox security settings)
If it does, you can use it to run Sage notebooks
- you'd need to run, in Sage'd top directory,
jupyter kernelspec install
local/var/lib/sage/venv-python3.9/share/jupyter/kernels/sagemath
(assuming you have python3.9 (else you'd need to adjust the path accordingly)
