New UI in Firefox v140 reverted to old after a few hours

After years of hoping for a dedicated new tab button in Firefox for iOS, my wishes were answered this morning when I installed the Firefox 140.2 on iOS. As explained in the release notes, there is "a sleeker, more intuitive Toolbar and Tab Tray — with smoother animations, simplified controls, and a modern look that feels right at home on iOS." What's more, it replaced the (IMO) useless "home" button with a BEAUTIFUL one-tap new tab button! I was overjoyed!

However, a few hours later, my Firefox UI has reverted back to the old way. It still claims to be on version 140.2, so I don't understand how that happened. As far as I can tell, there are no options within settings to get the new UI.

What happened, and how can I take advantage of the new UI?

Hi Blevy,

I'm excited to hear that you're eager to try out the new iOS toolbar. If you go back to the release notes, there's a disclaimer that the feature is part of a progressive roll out. We try to be cautious upon releasing a major change by applying gradual rollout like this, to ensure that we can contain issues that we may not notice before we roll it out to more users.

That said, the team is aiming for 100% release by version 141, which is scheduled to go out on July 22. There's also a possibility that you'll get to taste the new UI even before 141 release. So hang in there!

I would also get rid of the "Home" button. I would much prefer a "Bookmarks" button so I can get there in one touch, and a "Share" button. In fact, why can't I customize the toolbar.

I've been using Firefox as my default browser on my laptops for years and wanted to switch from Safari to Firefox on my iPhone. Safari though had those toolbar features while Firefox doesn't appear to, which is frustrating.
