I know this isn't a KANO problem, but was wondering if could possibly reach out to Facebook and get rid of this horrid waste of space. It's started happening ~4 days ago using Firefox 41.0.2.. I've sent a message to FB, but of course no response. I know one way of getting rid of it, but is only for "1" tab and it's really is a PIA to keep blocking it. Right click the toolbar select "Inspect Element" look for "toolbar container" right click> "delete node" and close the box all the way to right top is "X"
I would love it if we could actually do that, but even if we asked very politely I doubt Facebook would remove it. Hopefully they realize how annoying this is in a few days and revert it back. Good tips on how to hide it though!
If have Adblock Plus (which is a add-on for your browser) there is a way to block the toolbar for good or if wish to install it. Install Adblock Plus click on the icon select "go to filter preferences" make a group list then add this link to the right side filter box>> apps.facebook.com##._470m gone for good
Also I have gone off thelast update - it isnt working well for me - I thought it would be good for 3 day calendar - but its too busy - its trying to do too much at once
