Why does (only)Nightly erase(delete) clipboard contents when I close it on my Win 8.1 64 bit HP desktop?

After using Nightly for several months on a new HP Win 8.1 64-bit All-in-One desktop, I've noticed that if I have copied anything from Nightly to the clipboard, it disappears when Nightly is closed, and is not available to be pasted into any application. This includes graphics and text. I just recently realized that Nightly was the culprit when copying from the address bar before closing Nightly, in order to paste the location into Chrome or Firefox - it was gone! A little experimenting verified that it was the act of closing Nightly which cleaned out the clipboard - I just verified by copying this message, and pasting it into a text file, then closing Nightly only to find the clipboard empty when attempting to re-paste the same info into the same text file - gone! I find this uncomfortably reminiscent of past Windows "features" which drove us buggy!  ;)

HI Wrath_of_Wotan, What version of nightly did you see this start in? This can help isolate where this started. I also noticed that sometimes the clipboard will paste the item from two copies before. This may be another issue though.

Do you clear history on exit in nightly as well?

This happens because you run Firefox in Private Browsing mode.

Yes, this happens by design, because Firefox is clearing the clipboard after the private session is finished (e.g., by closing Firefox), in order to prevent the copied data to be able to get abused without the user's knowledge.
