Over the last few weeks we worked hard on getting the New Tab feature into Nightly builds. This feature displays a series of thumbnails of your most commonly visited sites (based on your Awesome bar) to make it easier for you to quickly move on to your next task.
We turned the New Tab feature on by default to make it easier for you to test on Aurora. We plan to turn the feature off again on February 16th (next Thursday). You can easily toggle the preference if you want to continue testing it on Aurora past the 16th. Just go to about:preferences and set ‘browser.newtab.url’ preference to ‘about:newtab’, ‘browser.newtabpage.enabled’ to ‘true’ and restart Firefox Aurora.
You can easily file bugs using the following link: https://bugzilla.mozilla.org/enter_bug.cgi?product=Firefox&component=General or read more about the open bugs here bug 455553.
You can also leave your feedback here if that’s easier (#newtab). We’re looking forward to your feedback!
