8992	FF: You can't delete placeholder using backspace key	Jakub Ś		"To reproduce:
1. Open placeholder plugin sample
2. Put cursor behind placeholder and try to delete it.
Result: you can't.

This is actually how Firefox works. **It does not allow for removing non-editable elements with backspace key**[[BR]]
Insert the below code in HTML page, open it in Firefox and try to delete placeholder.
{{{
<div contenteditable=""true"" style=""margin-bottom:25px; border:3px solid black;"">
<p>This is a <span contenteditable=""false"" data-cke-placeholder=""1"" class=""cke_placeholder"">[[sample placeholder]]</span>. You are using <a data-cke-saved-href=""http://ckeditor.com/"" href=""http://ckeditor.com/"">CKEditor</a>.</p>
<div>
}}}

**Perhaps CKEditor might introduce some code working around this issue**
