User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0
Build ID: 20151029151421

Steps to reproduce:

Take an image and drop it onto the desktop(amount varies but is within the single digits)

Actual results:

the browser freezes fully. A popup shows telling me that shock-wave flash has become unresponsive. even with no instance of flash running.

I can click "stop script" but it will just remain in an endless loop with the popup continuing to appear.

instead i had to force kill the browser.

Expected results:

nothing, it should have just let me continue my browsing.

Works fine for me using the latest Nightly on Windows 10.

Reporter, could you please let me know if you are still seeing the issue when:
- starting Firefox in safe mode
- starting Firefox with a new profile
- starting Firefox after a reset
Tried them all already, does it even when in safe mode.

to note, this happened only after the 42 update, ive even reinstalled flash fully and  changed drivers for my gpu to the newest ones since it started, so it can be pinned on the browser update causing it somehow
Blocks: windows-10
I still can't reproduce this on the latest Nightly or Firefox 42 - tested with and without an enabled Flash plugin.
