I've used Win 7/Vista's snipping tool for ages without any issues until this past month or two, when suddenly I find I can no longer use it within Firefox (v 25) for anything. As soon as I open it up (regardless of settings) it turns the screen black and so I can't see the portion I want to snip. I've tried changing various settings within it, and also within Firefox but nothing's worked. I switched off things like Adblock & Ghostery and tried it even without many of my usual add-ons running all to no avail. This seemed to only start with the last Firefox update possibly but as I don't use the tool that often I'm not too sure of the exact timing. I should point out the snipping tool works fine elsewhere within Windows - it's purely in Firefox I run into this issue :( Anyone else discovered this issue or have any suggestions on how I might fix it. A search on Google hasn't provided much help thus far, so hoping someone here can. Thanks
