snap bug

I'm running the latest ubuntu, and that ships with a snap version of firefox. When trying to launch notebook from a .py file. Everything works up until firefox tries to grab the html from /tmp. It can't see it. If you could add some option to save to a different dir than /tmp that would help. Also maybe describe this bug in the readme for other ubuntu users.

I did some digging

Looks like snap intentionally does not allow for it's packages to see the /tmp folder and thus it can't collect the html it needs.
Here is a link -> https://forum.snapcraft.io/t/accessing-tmp-from-snaps/22384 The link mentions how apparently firefox can't see /tmp but can see /Downloads.

Verification of problem

Sure enough if I copy over that html to downloads I can open it from terminal with firefox and it appears as expected.
