What is best way to remove "About:blank"?

if you use safari go to

Safari>Preferences

click on the general tab

and set your homepage to something other than About:blank

If you have accidentally saved the 'About:blank' in your bookmarks

you could remove it same as any other unwanted bookmark then it

would not be available as a default either...

Although I've encountered a saved About:blank in my bookmark

folder, it wasn't there originally. So it may have occurred due to a

saved History. ~ There are in-browser commands some versions

can use, such as 'about:config' among others; browser shortcuts

to change the default functions.

Seldom do my computing needs require a homepage in browser

to be set or run on launch; so I usually choose a blank option...

Of course my Macs generally have at least three browsers.

You could check your browser bookmarks to see if 'about:blank' is

a saved internal page in the browser; if so, just delete it.

Good luck & happy trails! 🙂

If your computer is randomly going to an 'about:blank' page, there may be

other indications of bad extensions or adware, or other things going on.

Rare but not unheard of, when I researched this topic yesterday; some

users who'd acquired bad copies of software from untoward sites online

had some issues as a result. Or poser sites offer doctored 'free' badware.

So the question does remain, if there IS anything else to detail this issue.

In any event...

Good luck & happy trails! 🙂

Care to elaborate?
