I don't see this bug. Can you try opening the attached page, and dropping the same text into the box, then pasting the text that gets output here? Are you using a non-english browser/locale for either browser?

The problem is reproduced in Firefox2.0-25.0a1 on ubuntu12.04(I did not check Firefox1.5 and earlier) So, The regression range of comment#1 is only for windows.

Upon thinking about this further, I'm wondering if this is a Chrome or WebKit bug. So far I'm only seeing evidence that this happens when dragging *from* a WebKit browser *to* Firefox. What happens when you do this from Firefox to Chrome? How about from Chrome to other applications? How about IE to Firefox?

Drag&drop from Firefox to Chrome - OK Drag&drop from IE to Firefox - OK Drag&drop from IE/Chrome/Firefox to other application (wordpad)- OK Mozilla/5.0 (Windows NT 6.0; rv:28.0) Gecko/20100101 Firefox/28.0 (20131030030201)

Dropping markup from Chrome to Firefox still produces these weird results. We've faced this issue while testing drag&drop integration. I'm assuming that issue should be within FF, since drop to IE works as expected. In addition Mihaela mentioned that this issue was not reproducible with FF4 (at Windows). All the tests made with FF29, UA: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:29.0) Gecko/20100101 Firefox/29.0. Dropping from Chrome to IE8 works fine. Dn from IE to FF can't be tested, since FF does not accept dropping content from IE - tested with IE8 and IE11. (Though e.g. IE11 accepts dropped markup from FF).
