Youtube mobile Safesearch is not working on Firefox23. How can I turn safesearch on?


How to reproduce: 1. visit www.youtube.com mobile site using a tablet 2. go to youtube setting and turn the Safe Search to On"

   (or edit PREF cookie's fms2 value to 30000)

3. search the word like "porn"

The result is not filtered.

My user agent is "Mozilla/5.0 (Android; Tablet; rv:23.0) Gecko/23.0 Firefox/23.0" on Nexus Tablet. You can also reproduce this issue just by changing the user agent and visit youtube mobile site on your PC.

Youtube mobile safe search is working in chrome browser. So I believe this issue is Firefox specific.


Additional System Details


  • User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.95 Safari/537.36

I'm able to replicate this on my mobile phone, interestingly though, Chrome, in the same phone (A nexus 4) has the same behavior.

So it looks like a problem on their side. Thinking about it, it's hard to tell how could this be related to the browser.

I would recommend rising the issue in the Youtube forum: http://productforums.google.com/forum/#!forum/youtube
