Permission Problem with Camera

more options

We have a customer using our SaaS solution running through Firefox 91.12.0 ESR. The web application we provide requires access to the camera on the local machine so we can capture a photo. We give them instructions and they configure their instance of Firefox to ALLOW access to the camera, along with several other adjustments (like allowing pop-ups, and no autofill).

However, whenever they restart Firefox the camera permission reverts back to the DEFAULT of Always Ask. The other settings adjustments we make, like pop-ups and no autofill stick around, but not the camera setting.

We've checked the PREF.js file in the Profile folder and that doesn't appear to be a problem. On our in-house machines we are running the same version of Windows and Firefox and cannot reproduce the problem.

The customer has recently applied the upgrade from an earlier version of Firefox ESR to 91.12.0. The customer has also imaged the PC and copied over to a large number of additional machines for use around their organization. This problem is causing a serious disruption to their deployment of the updated PC's as we work with them to try and troubleshoot the problem.

Any ideas on what to try would be appreciated.

If a particular website is involved, you could use the Permissions tab on the Page Info dialogue which you get with ctl+i. Near the bottom of that tab is Use the camera with 3 options.

I just found this draft response in one of my tabs, and I can't recall why I didn't post it. ??

When I test with one site, the permission is stored in the permissions.sqlite database file with the others in a manner that looks persistent. Is there anything in their configuration that might clear permissions or remove the file?

In Firefox's configuration, they could double check:

Settings > Privacy & Security > History

If this is not set to "Firefox will: Remember history" -- which should be fine -- they can select "Firefox will: Use custom settings for history" to show the details.

If the "Clear history when Firefox closes" box is ticked, click the Settings button to the right and make sure that "Site settings" is NOT ticked because that will flush the permissions.

From the about:config viewpoint, that corresponds to "privacy.clearOnShutdown.siteSettings" and it should have its default value of false.
