cannot enable location service
When I visit a particular web site it requests that I grant Firefox access to location services. When I attempt to, the site's interface takes me to (Apple) System Settings/Privacy & Security/Location Services and shows me the access status of the Firefox.app. The control next to it shows it as off. Clicking on the control to change it to on does nothing. The web site cannot access location services.
Location Services itself is on, as are permissions for several other apps (including Safari, which does not have this problem with this web site).
Within the Firefox apps own settings, location permissions for the site in question (scistarter.org) are set as Allow.
I'm on an iMac, running Tahoe 26.5. This problem does not happen on my iPhone running iOS 26.5.
Help?
