Firefox can’t find the file at /tmp/tempPlot*.html

[kaplinav]

Hello!

Problem

When I try to plot a graph (e.g. staticPlot.kt) after executing plot.makeFile() and opening Firefox browser, I get "File not found" message.

But the file exists at the specified path.

System:

• Ubuntu 24.04.4 LTS
• Firefox 151.0.2 (64-bit)

If I try to copy the path and open it in Google Chrome, everything works fine.

Possible cause:

The Firefox snap is sandboxed. The sandbox prohibits reading files outside of ~ and /var/www.

To check the list of running snap packages in Linux terminal
snap list

The result of executing the command in my case:

Possible solutions:

Try downloading another copy of Firefox or trying a different browser package: Link 1, Link 2

First of all, Plotly-kt now moved to be a part of VisionForge project (https://git.sciprog.center/kscience/visionforge or https://github.com/SciProgCentre/visionforge). I will update the disclamer.

As for the issue itself, it obviously could not be helped if browser isolation prohibits loading local pages. makeFile() has an optional argument that describes where specifically the file will be created. You can use it to bypass isolation.
