How do I disable private browsing in Firefox 18?
I Tried to look for something on
about:config, but did not find anything.
I found This aswer here, but I was unable to find that file on my computer.
I am using Firefox on Windows 7
Using the hosts file is really cludgy old tech and playing catchup after the fact.
You might want to try using DNS services with built in site blocking. OpenDNS does site blocking but it's more robust in commercial products. Researching this, I ran into Norton ConnectSafe (dns.norton.com), free for home use. It has porn and non-family blocking options with specific DNS numbers. They maintain the site list for you.
Ideally, you'd set the DNS servers on the router they don't have access to but it will affect all connected computers. DNS can also be set per PC though.
This won't avoid everything but would make your job easier?
