User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/20100101 Firefox/15.0.1 Build ID: 20120905151427 Steps to reproduce: On my website I have the social buttons for Twitter, Google+1 and Facebook like button in that order. Actual results: Twitter and Facebook like button displays but Google+1 doesn't appear. To confirm, I went to https://developers.google.com/+/plugins/+1button/?hl=en and the frame under +1 button which shows the example button and the code fail to display as well. The same behavior can be reproduced at the footer of this website as well. http://twittercounter.com/ Expected results: Testing on Chrome and stock android browser, all 3 social buttons including Google+1 appears. Only on Firefox, the Google+1 button doesn't display.
I get a a ridiculous amount of errors from Google  which is likely contributing to the issue here https://developers.google.com/_static/css/screen.css  http://jigsaw.w3.org/css-validator/validator?uri=https%3A%2F%2Fdevelopers.google.com%2F_static%2Fcss%2Fscreen.css&profile=css3&usermedium=all&warning=1&vextwarning=&lang=en#errors
Well, I'd like to be sure it's not us first.
Well the Google+1 button doesn't display only on FireFox Android. It works all other mobile browsers though, so I don't think it's evangelism bug. Not to mention that Firefox for Windows displays the +1 button despite those validator errors.
