Add editable CSS about markdown-viewer

[patdavid]

This would be fantastic, as I'm not aware of another markdown viewer for FF that allows custom CSS for the output.

As an alternative (until a modifiable CSS option is available), the Firefox add-on Greasemonkey can be used to customize the page. For an example script, you can look at this sample script (hosted as a gist on github).

Note: to allow GreaseMonkey to operate on local files, the setting "extensions.greasemonkey.fileIsGreasable" must be set to true. The setting is accessible via Firefox's "about:config" URI.

Edit:
Another workaround is to add a style sheet via the firefox addon "Stylish".
I simply wrote a style sheet that affects all markdown files using the rule:

@-moz-document regexp("^.*\.md") { ... }
