using XF version 1.3.1 It is not possible to copy a normal text from an E-mail from "Thunderbird" and paste it into "XF-Editor" at "Private Conversations". using Firefox version 30.0 Example: 1) write some text. 2) submit message. 3) edit message and delete some text. 4) paste some text from "Thunderbird" into the Editor. The strange thing is: sometimes it is possible to paste the text into the Editor, sometimes not. I am not sure how to re-produce it, but "copy/paste" via "Strg+C" and "Strg+V" is not working properly in the Editor.
