Why is there a blue box that appears on my macbookair that suddonly disables my spacebar? I can not seem to make it go away it interupts my work on a daily basis. How do I make it go away once and for all?

Try to disable full keyboard access using the steps here, Navigate your Mac using Full Keyboard Access - Apple Support (LB).

I hope this helps bc it did for me.

This usually means you have gotten Full Keyboard Access turned on by mistake. Go to Accessibility preferences and turn it off.

Well. if it were me I'd enter a known zip code and see where it takes me. But then, I'm prepared with multiple backups and Flash drives to reinstall the OS if the worst happens.

Maybe it's malware. Have you run MalwareBytes or DetectX Swift?

Maybe some add-on or extension you installed lately.

Whatever the source, it's some sort of search and that usually is prompted by you visiting a website.

That's a feature of the particular website you're visiting. It's a search utility for that site.
