Ext doesnt do anything.

Only site blocking addon working on my mobile device so far. Worked out a few learning curve kinks and now it's doing its job great.

Misspoke earlier, the extension works as it says, and well. Would be nice to not be able to disable it without the password but that's likely limited in scope for an extension.

my kids hate it me love its

Works just fine. However, I strongly dislike how it appears when one goes to a site one has blocked. It looks like you've been taken to some hack site. It would be MUCH BETTER if instead of the page heading being "Restricted Access" it said something like "This page/site has been block by the Block Site Firefox Addon."
Please, don't expect me to realize what is going on by seeing some stupid icon either. (I hate icons, but they're here to stay.) Secondly--although this may be an option--the screenshot shown in the example is white, while I get a BLACK screen (which, again, looks hackish).

Väga kasulik ja vajalik lisa. Väga hästi tehtud ja ilma probleemiteda

My kid just deleted the app extension, had password protection on and everything. Didnt even make it past 10 minutes.. sorely disappointed
