doesnt work on every explicit website.

Hello, I'm currently testing parental control systems to see which adult content tagging systems they respect. With all the adult content filters enabled, this extension fails to block sites based on various meta tags used by adult websites to identify themselves as such.
I've tested the following meta tags in use by adult websites and none of them cause the page to be blocked:
<meta name="rating" content="adult" />
<meta name="rating" content="mature" />
<meta name="RATING" content="RTA-5042-1996-1400-1577-RTA" />
<meta name="rating" content="RTA-5042-1996-1400-1577-RTA" />

This lets me access 18+ twitter profiles which would otherwise be blocked.

Also, all adult sites I've checked so far include at least one of these tags, so I think it makes sense to check for them.

Work perfectly!

i got this extension for my son to keep him safe from certain types of underage websites. i really like the pop up that comes up its is a helpful friendly reminder why kids should visit certain websites. however, for me i also has some issues blocking non dangerous non underage websites. i will most like have to turn it off to access some websites i know has been incorrectly blocked. while i really like this extension comparing to others similar Block sites extensions. i think it would be nice to edit or have password protected option for parents to allow white list good websites that are approved. And, based on the user manual on website.
8. Choose Password Protection "Yes" and fill in your desirable password into "Password" field.
9. Press "Save" button. I didn't see that option when I first download this extension. I don't know how to access the options page.

Only blocker that actually seems to work. And whatever it misses you can block or allow.

works fine:)

The Chrome version is good, but the Firefox version is outdated. Please update the extension. Also, please offer a contact information.
