Citation request triggers "Your cookies seem to be disabled." response

[welsberr]

Problem: I can't get Bibtex citations using PyScholar.

Replicating: Install PyScholar, run the example single-article Albert Einstein query without "--citation bt", which will succeed, and then again with "--citation bt" in the parameter list, and the Google Scholar page in Firefox (via geckodriver) complains that "Your cookies seem to be disabled." Cookies are not disabled in the browser.

Replicated on: Ubuntu 18.04, Anaconda Python 2.7, Firefox 60.0.2, and Windows 10, Anaconda Python 2.7. Firefox 60.0.1
