There is still some time until [Firefox 50 becomes stable in November 2016](https://wiki.mozilla.org/RapidRelease/Calendar), but as a noteworthy number of developers could use it already from September when it will promoted to [Firefox Developer Edition](https://www.mozilla.org/en-US/firefox/developer/) (in fact, I’m using it already with [Firefox Nightly](https://nightly.mozilla.org/)), I suppose it is not too early to point out that the following _firefoxPastingHack_ for pasting images will not be necessary (and even counterproductive) any more due to `clipboardData.items` being implemented in Firefox 50 (see [Mozilla Bug 906420](https://bugzilla.mozilla.org/show_bug.cgi?id=906420)):

This said, pasting an image into Discourse using Firefox 50 currently yields two to four (mostly three) instances of the same image being inserted:

This is due to the fact that the paste event contains both a _png_ and a _jpeg_ version of the image. Whether this is intended or not, is expected to be cleared very soon (in [Mozilla Bug 1290688](https://bugzilla.mozilla.org/show_bug.cgi?id=1290688)) and so we can anticipate a fix or (if it’s a feature) a hint on how to solve this conceptually.

Nice, perhaps we can switch to feature detection as opposed to user agent ?

That would be ideal. If not possible, it would suffice to add a version constraint here:

The issue is now fixed [in Discourse](https://github.com/discourse/discourse/commit/24201d4638884e57fec1d47fdfdf697e49f30f56) and [in Firefox](https://bugzilla.mozilla.org/show_bug.cgi?id=1290688#c15), so this topic can be closed.
