If you’re copying a text, you don’t want to paste it as is into another application. Instead, you want to make sure that the entire piece of text is there, and that it’s the same as when you copied it. That’s where the clipboard history manager for Mac comes in. It allows you to keep your clipboard contents, making it easy to reuse them in different applications.

As long as you have this extension installed, you can copy text anywhere, even to Safari, and then paste it into another application. You won’t have to do anything else to make sure the text is copied and pasted correctly.
