Twitter is blocked ?
Twitter used to work just fine for me but all of a sudden you have blocked twitter and i don't think it's malicious or wrong.
Our work around at school was to have the students remove and re-add their user accounts to the Chromebooks. That fixed the false positive for all of youtube.com.
Today, MetaCert let me know they released a new version 0.10.15 that should fix the problem.
Can you also please confirm that you have "Safe Browsing" enabled and not "Just for Kids"?
Actually can you please take a screen shot of your entire browser as we are now unable to reproduce this? We'd like to see what the URL is. Is it blocking youtube.com ? that is, the domain and not just a link?
Great news! Thanks for the update. Looking forward to the fix.
This is a bug. We are working hard to fix this for people who are being blocked from Twitter, Facebook and YouTube.
Can you please provide us with a screen shot of the warning page - include the entire browser. Many thanks..
