I was able to paste something today. But, only after I first failed... However, I noticed that I had to "clean" what I ended up pasting. For instance, I copied the contents of the post that I had created, so I could paste in some links and then repaste it as a whole, since I didn't know it was "fixed", and I noticed that unprinted characters were getting pasted/copied. So, I pasted in another app as clean unformatted text and was then able to paste without these non-printing characters showing up.

Thanks for whatever fixes are under construction! We'll see how it goes.

(Firefox, latest version. Flash got updated too, by the way. Getting some weird bugginess with it, but probably unrelated.)
