Mozilla’s UX-Nightly build of Firefox
15 March, 2012 § 39 Comments
Have you heard of our UX Nightly build of Firefox? Yes? No? Either answer is good, because even if you knew about it before, you should get reacquainted with it now.
Long story short, there was a bug that broke nightly updates for users of UX Nightly. So starting right now, as in, RIGHT NOW, download an updated UX Nightly build!
What is the UX branch?
Ironically, it is the branch of Firefox with potentially the worst user experience :D. The UX Nightly branch is the branch where developers can test out new features and experience them for a while before knowing if it’s something we want to ship. Currently, there are patches on the UX Nightly for removing redundant text in tab titles, parts of the new Australis theme, and enhancements for the New Tab page.
Any other reason to download?
Glad you asked. Yes, there is another reason to download. The first 10 people that download it now and send me a screenshot of their about:support page (hence, proving that they have updated) will get a nice postcard in the mail signed by as many members of the UX team that I can meet up with (at least three, I promise to try my best).
Please send your email to REDACTED and include a mailing address if you would like a postcard. If it’s too hard for me to send you the postcard (location/price/who-knows), then I’ll try to send you a scanned copy of the postcard I would have sent.
Contest update
Wow, that was fast. In less than an hour I received the first 10 entries. I’ll upload a scanned image here for others who would like to see the postcard 🙂
JAWS 
Is it possible to install it side by side with Firefox 22? I want to try Firefox UX but I want to have a working browser in my machine. This is on Windows.
Yes, by default they will share the same data but you can run Firefox with separate profiles if you want to run both of them at the same time. See https://msujaws.wordpress.com/2011/06/29/running-multiple-versions-of-firefox-simultaneously/ for more info.
Hello,
does anybody know when UX is ready to appear as aurora and in german?
Hopefully in about 10 weeks.
What happened to the user interface bar at the top? I much prefer the more Chrome looking buttons as it was a week or two ago.
Atleast allow us to move the page refresh/stop button out of the address bar, I hit refresh ALOT and that small integrated button is just way too close to the web history V arrow.
The navigational buttons were merged together because they form a cohesive unit. I expect that somebody will create an add-on to allow the stop and reload button to be placed outside of the location bar, however I don’t see one on addons.mozilla.org yet.
But your comment points out that some people think the reload button as-is is too hard to hit, and it would be better for all users if we can make that experience better. I hope we can make some strides on that in the near future.
I’m sorry, I should have included a screenshot.
(Much prefer how I had it looking before the automatic update)
This is what happened to my Firefox UX after an automatic update sometime last week.
Was this an intentional design change for the navigation bar or am I experiencing some kinda bug?
Thank you for the reply.
i think it would look much better on OS X if the stoplight buttons were moved down and to the right, like in chrome
Yes, this is a known issue and is tracked at http://bugzil.la/851652

Can you try updating? I haven’t seen this issue before.
I am not having this problem on my Mac OSX 10.7.5 Nightly UX browser
Is there a chance to have Win64 builds of UX-Nightly (like the regular Nightly builds)?
Sorry, I don’t see any Win64 builds of the UX branch in the build output directory.
a bug with broken tabs, disappeared after update!
Cheers!
A noob question, is the UX is as safe as stable build? Latest security fixes applies to UX also?
UX Nightly is just as safe as Firefox Nightly. Code changes for Firefox Nightly get merged to UX Nightly a few times per day.
Is there a PPA for Debian distros? I know that firefox-trunk is for Nightly, but I don’t see one for UX.
I’m not sure of the answer to this question. The build process for UX Nightly follows the same for regular Nightly. You may find the build you are looking for at http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-ux/
Hmm. Thanks, I’ll see what I can do about it.
