Trying to access https://www.locast.org. but my location is blocked. I want to add\change\edit a permission for the above website to allow. I have previously blocked requests for my location in Permissions => Location => Settings. I have now unchecked this. I have deleted the relevant cookies using the sites shield menu. I am unable to get the site to prompt me to allow location nor can I manually add the site to the in Permissions => Location => Settings. I expect this to be in about:config but no idea where. How can I correct this?
