Bug 237050

Screenshot of the window that briefly appears after CMD+S

I've recently lost the ability to save web pages in Safari 15 as webarchive. When I try to do so, I get the dialog box where I would normally choose a destination folder for saving the webarchive file. However, no navigation is possible on the dialog, the whole window disabled and nothing is clickable, making the “boing” sound wherever I click. The only possible option is pressing ESC to go back (the "Cancel" button doesn't work either).

The problem is reported by me and others here:

And there are a few more posts regarding the issue on the Web.

One thing I notice is immediately after pressing CMD+S to save the page, a window pops up on the bottom left of my screen for a very brief split second before disappearing, after which the normal Safari Save dialog (the one that doesn’t work) comes up. One user in the aforementioned thread managed to get a screenshot of this “phantom” windows that pops up and disappears. I’ve attached it to this report.

On my MacBook Air M1 with Safari 14 everything works fine.

Thanks,
Miguel Barrosa
