No "open in browser" after copy and paste

[Patti]

I have an html page that is linked to an external style sheet. This html page shows “open in browser” when I right click, and opens as desired.
I then copied and pasted the entire html page into a new file, and renamed it(i do this to keep track of changes). After saving the new file, I am not getting the “open in browser” option.
What am I missing?

I fixed my problem, it was a newbie mistake. I didn’t type “.html” after the new name! oops!
