Seeing Missing Tabs? A Recent Browser Security Change May Be the Cause.
Intro
Google Chrome, Mozilla Firefox, and Microsoft Edge have introduced a security feature that prompts you to allow or block local network access.
If “Block” is selected, the browser may remember the choice and won’t prompt again, which can prevent tabs from loading.
Choosing “Allow” ensures your tabs display properly.
If “Block” is selected, tabs may not appear or load correctly.
