please add an option to completely block access of any third party website to LAN

Also chrome is trying to add it in their browser (now they added the option to block access from insecure website

As recent malicious activities against router login pages that are exist for several years this optional option will be great.

Also an option to block localhost also will be great addition.

Thanks.

uBlockOrigin/uBlock-issues#1070

Block insecure private network requests.

Prevents non-secure contexts from making sub-resource requests to more-private IP addresses. An IP address IP1 is more private than IP2 if 1) IP1 is localhost and IP2 is not, or 2) IP1 is private and IP2 is public.

Or if it is hard to do this in webview, at least please look into adding an option to completely block access to LAN IPs from browser so we can enable it and if we needed to access LAN, we can temporarily disable it.

Also same with localhost will be great.

Thank you very much.

Currently i can block access completely in firefox using ublock origin's advanced mode with these rules.

• 127.0.0.1 * block
• 192.168.0.x * block
• 192.168.1.x * block
• 192.168.43.x * block

Although these addresses only blocks access to my router web panel.
