Last solution found.

Fix, the initialisation of label field in IE and Firefox.

At the creation, title attribute does not work in Firefox, when you do not select all the text in a <p> element.

Problem is after line 2354 ( editor._doc.execCommand('createlink', false, f_href); ), link is never found in Firefox, editor.getParentElement() return the <p> parent element instead of the <a>
