Open Tabs/Pages in Safari lose content and URL over time

I've been experiencing exactly the same thing since updating to Sonoma. It's super annoying. What works for me right now (most of the time but not always) is to hit the "back" button and that reloads the page, but it's still annoying and most definitely a bug that needs fixing. I hope Apple gets around to it quickly.

I agree it's a Safari 17.1 issue. And in fact, there are quite a number of issues with Safari these days and to me it feels like it's going backwards and degrading, which is sad.

As an adjunct, it may have to do with security changes that some websites implement and their interaction with Safari extensions that we install to remove unwanted advertising. Happens with CNN a lot. It may be a way for websites to "force" ads on us by limiting what advertising-blocking extensions we use! Just a theory.

It is indeed very often. It happens to me a couple of times a day!

Happens in the 13.6.1 version of Ventura as well. It's likely a Safari 17.1 issue and not a Sonoma or Ventura OS issue.

They really need to fix this. I've seen it since the introduction of tab groups. Some Safari versions were better than others. The latest version with profiles has gotten much worse. The only workaround is to right-click on the now blank tab and "duplicate" it. The new tab will reload with the content.

Andrew, just for some more information, I am only using two Safari extensions - Grammarly and Hush. And that's it. Are you using any of those two? If you do then we could say that perhaps one of them it causing the issue. If not, then my theory is still that it's a bug in Safari.

I just installed Sonoma and am experiencing the same issue, as well as glitches when using Gmail + slow load times.

Did you find a solution to the problem?

I use Grammarly. I just turned it off. Will update what happens later.

Upgrading to Safari 17.2.1 hasn't solved the issue for me.
