it's an issue with your Firefox setup (or a new feature), not a general Firefox/Sage feature/bug. E.g. on Gentoo with its Firefox (97.0.1) I can do ./sage -n jupyter ../sage-clang/u1.ipynb and u1 gets opened, although I see a warning: [W 08:45:52.113 NotebookApp] Notebook u1.ipynb is not trusted I can remove this warning by running in Sage's shell (i.e. at ./sage -sh prompt) jupyter trust u1.ipynb By the way, I can see the same kind of error as you describe on ChromeOS (running Sage in a VM) There "./sage -n jupyter" works, and opens the directory in Chrome browser, but "./sage -n jupyter u1.ipynb" errors out with "permission denied" Apparently some kind of sandboxing goes on here. You might try that "jupyter trust <nb name>" as above, and see if it helps. Also, I'd try installing jupyterlab make jupyterlab which is actually more up to date than the classic (and deprecated by upstream) Jupyter notebook, and see if the error goes away. > > On Monday, March 28, 2022 at 12:29:46 PM UTC-4 dim...@gmail.com wrote: >> >> On Mon, Mar 28, 2022 at 4:22 PM Henri Girard <henri....@gmail.com> wrote: >> > >> > https://github.com/jupyter/notebook/issues/1979 >> > >> > Maybe this issue ? >> >> no, that is about jupyter notebook server. >> >> Here, the issue is how to bypass the intermediate step of launching >> a notebook server, and open a particular notebook directly. >> In some environment this can be done by just clicking on a notebook >> file in a file browser. >> E.g. this can be used to run notebooks in VSCode (see >> https://trac.sagemath.org/ticket/30484) >> >> >> >> > >> > Le 28/03/2022 à 15:41, Dima Pasechnik a écrit : >> > > On Mon, Mar 28, 2022 at 2:18 PM brett stevens <bret...@gmail.com> wrote: >> > >> I am running Ubuntu 21.10 on a Lenovo Thinkpad X1 Tablet.
