I can’t seem to find any way to import the bib entries provided by google scholar to JabRef directly. You can enable the Import into BibTex link from the preferences but it streams the bib file as text/plain which opens up in the browser. You can save it and import it but that wastes a lot of clicks. The easiest option is to copy-paste all the text into a new JabRef entry (Ctrl+N). The default settings leave the double curly braces in the title (to preserve case) which can be removed by enabling the Remove double braces… checkbox in the File tab of Options/Preferences. This works for JabRef 2.5.
