I have also faced this type of problem in ago. But when i browsed into https://goo.gl/L0LV8e then i have came out from this problem. I will suggest you to browse into 'Safe Mode' ...

Thank You... :)

How exactly are you copying the image, and from where?

When you copy an image in Firefox, the clipboard includes not only the bitmap itself but also a fragment of HTML to embed the image. When pasting, Firefox sometimes/often/usually (?) will give the receiving page the HTML fragment instead of the bitmap, and if the site does not want that, then you get no image pasted.

We discussed seeing this problem on Twitter recently: Firefox copies images into clipboard in a weird format?

On the other hand, if you copy an image from another image display application such as the Windows Paint program (open image, Ctrl+a to select all, Ctrl+c to copy), then paste into the same site, Firefox won't have any HTML to give the site and should instead try giving it the bitmap data.

Not sure if that helps clarify the situation, or raises more questions.

It doesn't really matter where I try to copy/paste from. Right now I'm trying to copy/paste with the oneNote clipping tool, which works fine on Chrome. Also, if I go ahead and copy an image normally, it still doesn't show up when I paste it in Firefox. Anyone knows about a fix for this? Shouldn't be impossible since all the other browsers are doing it.

Unfortunately, it is up to each individual website to support pasting images: it needs to be explicitly scripted. For example, you should be able to copy/paste from Windows Paint into a new Gmail mess, or paste a screenshot into http://snag.gy/.

If you think a particular site should work in Firefox but it is not working for you, can you identify the problem site(s)?

The biggest problem for me is the Facebook chat system Messenger. The problem is both on Facebook's site and the stand-alone Messenger.com. I do not use the copy/paste much besides in those sites. But I use it a lot on tho.
