Why using `GLOBAL` in source code?

[foray1010]

What does it refer to?
If it is useful, I suggest to use typeof GLOBAL === 'undefined' to check if it exists, because it causes error when using strict mode

It is used when testing in Node.js. It refers to the global object.
I replaced it with a this keyword.
Let me know if it works.

It works now, thanks!

I'm glad that it's useful. I downloaded the extension. Never had one for bookmarks.
I like that it does not use memory when not being used.
