Safari Version 18.4 reloads web pages upon Tab Group change.

[Koloa]

Since upgrading to macOS 15.4 yesterday, which came with Safari Version 18.4 (20621.1.15.11.10), I noticed that if I select a tab in a different tab-group, that tab will reload from the server before it displays. Selecting different tabs within the same tab group does not do this.

This is particularly annoying for instances where you may have a web form partially filled out in one tab group, go to another tab group, and then return, as the page-reload will (in many cases) completely erase anything you may have written.

That happened here, as I was posting this comment...as a test, I selected another tab in another tab group, then came back to this tab, and sure enough, this comment was vanished. Thankfully, the forum software saw I had a draft that was saved and allowed me to continue, but, a lot of sites don't or can't do that.

This is new behaviour, and I'm not sure if there's a way to work around it.

Looks like this is also the behaviour in the Safari Technical Preview (Release 215 (Safari 18.4, WebKit 20622.1.6.111.4)) - and I probably should have noticed it there first...

Anyone else notice this? Seems pretty consistent and only came about after yesterday's upgrade to 15.4.

Here Safari forgot that it had profiles activated and all saved tab groups were lost. It still does not seem to be a good idea to use features that will be "forgotten" over upgrade.

I noticed the same. Safari has to reload them all each time. Crazy. Same behaviour on iPad 18.4.


I guess none of the beta testers used Safari. Thanks beta testers.

Same exact issue on my 2020 MacBook Air M1, it's such an annoyance 😤
Definitely needs a corrective update asap...

I was just about to create a thread about this, it's infuriating. Sending a bug report now.
