I am on Safari 26 beta on macOS 15.6 Sequoia but will be downgrading as there is a big lag when opening a new tab and you begin immediately typing (iMac M3 10-core CPU/24 GB RAM) which never happened on the stable release. Too much of an annoyance to keep it - but can confirm compact tabs are still there. In fact the whole UI except for the new tab drop down/suggestions is identical)

Tabs are still there, but you cannot close them by clicking the dot, you have to use ⌘ W, nor can you click into the search bar to type.

I'm pretty sure thats a bug, on the current release of Safari Technology Preview the same thing happens, I create a new tab and it won't let me click on the address bar to enter a URL, so there is literally no way to navigate anywhere. I quit and re-open and then it works as it should

The address bar is unusable when a website is opened in compact tab view but tabs can be closed with right click menu. And new tabs can be opened with the + in the upper right corner. Technology Preview is not affected. @CheesePuff

It has the bug at least since Beta 3 and 15.7 RC2+3. I read it in another thread. Don't know for other versions. I have installed Beta 1 in 15.6 shortly before 15.7 RC1 had been released. I never used the Compact Tab view. I only tested it, when someone mentioned the bug, who also had 15.7 and Beta 3 installed.


Safari 26 Beta 4 for Sonoma (14.6 and higher):

Since the latest beta for Safari 26, the bookmarks side bar, has been overhauled, and the once simple task of ordering websites, and collapsing folders has been replaced with a nice looking, but useless sidebar view.

Is the same for macOS Tahoe. Tempted to download the Tech Preview Safari instead.

Surprised no one else has had this issue. I decided to do a a full erase, and reinstall. With most of my stuff online, it takes 1 hour to reinstall, and another 30 mins to configure to my specs. I had been doing some python learning, and had a few python apps etc on my MBP, so good way to rid myself and clean up the system.

There are not many people interested in Betas for Sequoia anymore, 15.7 RC4 had been released today.

I don't use the sidebar and Safari is not even my main browser. The latest Technology Preview 226 got the same compact tab view bug by the way. But the sidebar looks different, there are no images of recently added bookmarks and the folders all have just the same folder icons.
