I was confused, because when reinstalling my home Desktop, I found that Google Chrome had a ‘double arrow’ to represent ‘more’ in the extensions bar.
Another computer I had didn’t have this, and still had a mess of extensions.
How did I fix this?
You can resize the ‘extensions’ toolbar in Google Chrome. A page I found here tells you that you can resize the toolbar.
Jeez, that’s awfully easy, now that I know about it..
