I've proposed a fix for this on https://trac.sagemath.org/ticket/33592
(there is no reason to use temp files, IMHO)
so we add c.NotebookApp.use_redirect_file=False to the corresponing config file.
Needs review.

I spoke to soon. :-) My solution makes the Ubuntu Jupyter work OK but
```sage -n``` does not work. For SageMath's jupyter I needed to make the same
change in ```$SAGE_ROOT/local/etc/jupyter/jupyter_notebook_config.py```

@dim I installed Ubuntu's jupyter and I am getting the same problem there so I
agree this is not a SageMath problem. I will post my question to an
appropriate forum. If I find a solution, I will report the fix here.
@HG, I tried setting ```c.NotebookApp.open_browser = True`` but it did not fix
the problem. But thank you for the reference to that thread as it still may be
related.

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)

I am running Ubuntu 21.10 on a Lenovo Thinkpad X1 Tablet. I installed SageMath
on my computer by cloning the git repository. I compiled sage using directions
in README.md. The most recent version I compiled was SageMath 9.4. I use
Firefox 98.0.2 (64-bit) as my browser.
When I run ```sage -n jupyter file.ipynb```
Such a way of opening a particular notebook is not supported, at least it
does not seem to be documented (in sage -n --help).
Needless so say, "sage -n" opens a page with the current directory
listed, and you can
then click on a particular notebook to open.
A new tab opens in firefox with address ```file:///tmp/tmp9csp8qpp.html``` but
Firefox reports
File not found
Firefox can’t find the file at
/tmp/tmp9csp8qpp.html.
Check the file name for capitalization or other typing errors.
Check to see if the file was moved, renamed or deleted.
However the file does exist. ```ls -l /tmp/tmp9csp8qpp.html``` returns
-rw------- 1 brett brett 751 Mar 25 10:15 /tmp/tmp9csp8qpp.html
If I open the file in Firefox directly using ```Open File...``` from the File
menu everything works fine.
When I run ```sage -n jupyter file.ipynb``` I get some other links in the
terminal to use for opening the jupyter session in my browser:
To access the notebook, open this file in a browser:
file:///home/brett/.local/share/jupyter/runtime/nbserver-101452-open.html
Or copy and paste one of these URLs:
http://hamm:8888/?token=cb4036e78faba0faa3bd0d50b73cc7a94e302196c474d878
or http://127.0.0.1:8888/?token=cb4036e78faba0faa3bd0d50b73cc7a94e302196c474d878
If I open the first of these, Firefox reports
Access to the file was denied
The file at
/home/brett/.local/share/jupyter/runtime/nbserver-101452-open.html
is not readable.
It may have been removed, moved, or file permissions may be preventing access.
However I have both read and write privileges for this file: ```ls -l
/home/brett/.local/share/jupyter/runtime/nbserver-101452-open.html``` returns
-rw-rw-r-- 1 brett brett 667 Mar 25 10:15
/home/brett/.local/share/jupyter/runtime/nbserver-101452-open.html
I tried changing the privileges to include ```x``` but Firefox still will not
open it.
Like above if I open the file in Firefox using ```Open File...``` from the File
menu everything works fine.
