CurrentPageToBibTeX от Jonas Mönnig

Generates a BibTeX entry for the currently opened page. The Add-on tries to extract author name, title and publishing year from the website. If mulitiple matches are found for the extracted values, a click on the currently used one will open a menu with options to choose from.
Version 1.0 introduces a template system but requires Firefox 48. (The default template is not plain BibTeX but BibLaTeX because the latter makes it easier to cite a webpage)
