set subject when sharing links

[ghost]

When sharing links from Firefox via longpress menu the subject of the generated email is empty. Should inlcude the link text if known and/or url.

It looks like the only information that Firefox is relaying is the URL itself as text. The only thing I could do is to also show the URL (or the beginning of it) in the email subject.

Same here, the URL seems like the only piece of information available. You could strip https{0,1}://www. away and url.decode it (things like %3D) .
