'File not found' using OSWeb run and quick run (ubuntu, firefox)

Wouter

Hi everyone,

Whenever I click on the run or quick run button, my browser is triggered to open a temp file such as "file:///tmp/tmppi092s1k.html" . However, this file doesn't exist. Ticking 'Bypass compatibility check' doesn't change this behavior.

Using the OSWeb & JATOS Control panel, I can export an html which can be opened and runs.

The Opensesame console just says:

In [1]: external js =

Is there something off with my install? I'm running OS 4.0.10, and Firefox 118.0.2, on Ubuntu 23.04

Thanks!

Hi @Wouter ,

This is because you're running Firefox as a snap package, which doesn't have access to the local file system. If you copy-paste the local URL into a different browser, you'll see that it works. Unfortunately there is no way (that I know of) to have this work with the Firefox snap.

That indeed worked, thanks! (chromium as a snap has the same problem, but non-snap installations of chrome worked)

A very personal feature request would then be to be able to choose which browser to run the experiment in from the OSweb settings. There might be other use cases where this is very helpful.

Anyway, my problem is solved for now, thanks!
