Comment 11 for bug 1179596

I can confirm that changing the UA string makes mobile.twitter.com work much better on Ubuntu Touch but couldn't find the right combination to make it work completely and look right. See bug https://bugs.launchpad.net/bugs/1190212

Setting UA String to any of these fixed the scrolling issue on the main list of tweets view:
 Mozilla/5.0 (Ubuntu like Android; Mobile; rv:13.0) Gecko/13.0 Firefox/13.0
 Mozilla/5.0 (Ubuntu; Android 4.0.4; Ubuntu Touch build) AppleWebKit/534.46 (KHTML, like Gecko) Version/1.0 Mobile Safari/534.46
 Mozilla/5.0 (Mobile; rv:18.0) Gecko/18.0 Firefox/18.0
However when clicking on a link in a tweet it wouldn't open.

Setting UA String to "", I could get all functionality working in twitter, including clicking a link opened the page in the new tab. The fonts looks bad and I had to manually go to mobile.twitter.com as it wasn't redirected automatically.
