Firefox issues

[RFMV34]

There are several problems in Firefox. I got the latest one.

• indent/outdent does not work
• can not change cursor position using mouse or select text in link dropdown
• long word is not wrapping

For the last point
word-wrap: break-word;
should be enough for fate-edit-target.
And indent/outdent is related to Indents the line containing the selection or insertion point. In Firefox, if the selection spans multiple lines at different levels of indentation, only the least indented lines in the selection will be indented. https://developer.mozilla.org/en-US/docs/Web/API/Document/execCommand
