local network access, site permissions, Firefox security

Learn why Firefox now asks permission before allowing sites to access your personal device or local network.

To better protect your privacy and security, Firefox includes permissions that control whether websites can access apps and services on your local network and local device. This change stops websites from exploiting them without your knowledge. [[Template:progressiverollout]] =Why is Firefox adding these permissions?= Websites can attempt to access your personal device —such as your computer or local network— and connected devices —such as routers, printers and local web servers— without your permission. Malicious sites have used these capabilities to track you or scan for vulnerable devices. To keep you safe and help you stay in control of your data and devices, Firefox now asks for your permission when a site tries to connect to your device or local network. =What to expect when a site requests access= When a website tries to access your device or local network, Firefox will display a {menu permission prompt} similar to those for accessing your {menu camera} or {menu microphone}. You can choose to: *{button Allow}access for that visit *{button Block}access for that visit You can also choose to have Firefox remember your decision for all future visits. You can change it anytime in Settings. ==What is considered ”device apps and services”?== "Device apps and services" are your personal computer and all the applications installed on it. ==What is considered a "local network device"?== Local network devices are any hardware connected to the same local network as your device. This includes: *Routers *Printers *File servers *Smart TVs *Media streamers *IoT (Internet of Things) devices Accessing these devices over the network could allow websites to interact with or retrieve data from them. A permission check helps prevent sites from doing so without your knowledge. =Manage access permissions to your device and local network= When a site tries to access other apps and services on your device or your local network, Firefox will show a permission prompt near the address bar, asking you to allow permission. For {menu Device apps and services}, the prompt looks like this: [[Image:devicepermissionschanged]] For {menu Local network devices}, the prompt looks like this: [[Image:localnetworkchanges]] {note}'''Tip''': If you want Firefox to remember your choice for the site for all future visits, you can also check the {button Don’t ask again for this site} box.{/note} ==Configure access permissions== #[[Template:optionspreferences]] #Go to the {menu Privacy & Security} panel. #Scroll down to the {menu Permissions} section. #Find {menu Device apps and services}, and click {button Settings...} #Here you’ll see a list of sites that have requested this permission. #Use the dropdown menu next to each site to change access. #Find {menu Local network devices}, click {button Settings}, and repeat steps 5-6.
