Qgis2web writes to /tmp - Firefox/snap can't read this. about qgis2web HOT 5 OPEN

Can you recommend a change to qgis2web? or is your issue aimed at providing advice for future users?

First it was a report so anyone else getting the same problem might find the reason, and to inform the devs about it. Secondly, to trigger discussion of how (if its worth it) to fix it. It might just be something worth putting as a note in the documentation, that QGIS and the user's browser must be able to access the folder where the map is written (default /tmp) and this might be problematic if either are running in some sort of containerised or sandboxed environment (snap, docker,...).

I will consider notifying the user before exporting, perhaps in a note next to the folder choice or in a "?" icon. to click. Thank you.

An alternative (and this is a much bigger enhancement) might be for qgis2web to launch a small asynchronous web server running on high port (eg 8888), and for the map outputs to be written to be served by that, and then launching the browser at http://localhost:8888/qgis2web/map1 - this should work as long as the browser is on the same host, but it does mean complexity at the qgis2web end managing the server. But if you want to make work for yourself... :)

This approach would have other wide-ranging benefits. The current preview or export running only as browsing a local file leads to security issues.
