Andreas M. reports:

today I was once again frustrated after finding my clipboard being cleared after restarting Aurora 12.0a2.

So I decided to trace that issue and ultimatedly figured out that disabling Thumbnail Zoom Plus 1.6.0 solves it.

But: Disabling all of the addons below while having Thumbnail Zoom Plus 1.6.0 enabled also does the trick:
InstantFox 2.6.1
LastTab 3.0t3.1
Scriptish 0.1.7
Status-4-Evar 2012.01.14.17
Tab Utilities 1.2pre18
ViewSourceWith 0.9.1.1

...

I'm not sure in which version of Firefox I first recognized this, but since I only recently went from 11 to 12 I don't think, this is a new bug in version 12. Also, this happens in both, Win7 & XP.

Steps to reproduce:
1) Start FF
2) Copy something in from within Firefox (webpage/location bar/search bar). If the clipboard already contained something before FF was started, this will not be cleared. Only things that FF itself put there are affected.
3) Close FF.
The clipboard isn't cleared on startup, when hovering over a thumbnail or when changing tabs. Whether this happens at random... I'm not sure, but I don't think so.

...

Pasting anywhere in FF and to other applications works fine as long as I do not close FF. The clipboard is cleared after exiting FF. Also, while experimenting which addon configuration produces this issue, I noticed that there is a very short time window after clicking on the [x] where pasting to other apps still works. So from my feeling (and limited knowledge of programming), the clearing doesn't happen onClose but somewhen later.

About Private Browsing: Yes, I use PB once in a while and noticed this there, too, but I also think this is intentional for privacy reasons. The issue at hand is not related to PB and happens in normal use.
