This may be a silly question but ....
As I remember, my Home page "House" has always been a solid black symbol. Now it has become just a black outline!
It appears that the function has not changed but does it matter, how did I do it & should I change it back? (If so, how?)
I have not intentionally changed my browser. I thought that I was using Chrome but perhaps I was just using basic Google and have not activated Chrome. How do I tell? (sorry to be so ignorant)
"but perhaps I was just using basic Google"
Google is a company. It's two most popular products are the Google search engine, which is available regardless of what browser you are using, and Chrome, which is a browser. There's no such thing a s basic google.
Chrome is updated quietly in the background from time to time.
It's quite possible that Google have changed the Home button icon recently.
In any case, it really doesn't matter.
