For folks helping with Firefox related documentation

• Set bugs to dev-doc-complete

Features to document

IDBFactory.open() has a proprietary options object that has been removed. Action is to update BCD and docs to reflect this.

Looks like this is a removal of a very legacy item that has been disabled for ages. I think we tidy the docs and add a BCD entry for the options.
