Https Everywhere kills Copy'n'paste in Firefox 22.0

Since installing https everywhere version 3, I've noticed that when attempting to copy and paste any content from within any webpage (URL, body of text, etc.) that it will not paste into the body of an email, Windows' own text editors, another open tab's page, etc. I am currently using Win 7 Home Premium with all the latest updates. Copying and pasting within a webpage or within an open tab usually (but not consistently) works.

I'm not a hacker or a programmer. Just a user who wants to be secure and thought you should know!
