About the security content of Safari 16.3

Thanks for letting us know, Sidachovmike,

Are you saying that the Favorites or Frequently Visited aren't available when you open a new tab in Safari? We just want to be sure that we're on the same page with you.

Are you able to customize your Safari Settings? This article will show you how: Customize the Safari browser window on Mac - Apple Support

"Customize the tab bar

1. In the Safari app  on your Mac, choose Safari > Preferences, then click Tabs.
2. Choose where to put tabs.

• Compact: Tabs move up to the toolbar. The active tab is the Smart Search field.
• Separate: Tabs remain in the tab bar, under the toolbar.

See Change Tabs preferences in Safari."

We look forward to your reply.

Take care!

Hi Sidachovmike,

Thanks for connecting with us here in Apple Support Communities. Have you had the chance to restart your Mac since noticing this behavior when using Safari? If not, please do so as this may help to address the issue you're facing.

We'd also suggest that you try starting up your Mac in safe mode to see if the issue occurs there as well. You can see how to do in the link provided. See: Start up your Mac in safe mode

Before you begin

To start up your Mac in safe mode, you need to know what type of Mac you have.

On your Mac, choose Apple menu  > About This Mac.

2. Look at the information in the window to determine what type of Mac you have:

If you see an item labeled Chip, followed by the name of the chip, you have a Mac with Apple silicon.

If you see an item labeled Processor, followed by the name of an Intel processor, you have an Intel-based Mac.

3. Use the corresponding set of instructions below to start up your Mac in safe mode.

Start up your Mac with Apple silicon in safe mode

On your Mac, choose Apple menu  > Shut Down.

2. Wait for your Mac to shut down completely. A Mac is completely shut down when the screen is black and any lights (including in the Touch Bar) are off.

3. Press and hold the power button on your Mac until “Loading startup options” appears.

4. Select a volume.

5. Press and hold the Shift key, then click Continue in Safe Mode.

6. The computer restarts automatically. When the login window appears, you should see “Safe Boot” in the menu bar.

Start up your Intel-based Mac in safe mode

1. Turn on or restart your Mac, then immediately press and hold the Shift key until you see the login window.

2. Log in to your Mac.

3. You might be asked to log in again.

4. On either the first or second login window, you should see “Safe Boot” in the menu bar.

Keep in mind that starting in safe mode will take a little longer than normal, because it verifies and repairs the directory, cleans caches, and loads only Apple-critical items.

Kind regards.
