The Google Scholar Button extension for Firefox helps users quickly access Google Scholar for research purposes. It allows you to search for scholarly articles, find full-text versions, format citations, and save articles to your Google Scholar library. It is especially useful for students and researchers, providing a seamless way to retrieve academic papers directly from any webpage. You can easily transfer queries from web searches, find resources in your university library, and even access case law.

Works great, convenient for students

This review could be 5 stars if I could locate the button on Mac Firefox/Mozilla. Locating the button is not straight forward however eventually I could do it on the personal PC. Then I spent >1 hr to search on Mac Firefox and on internet to find the button on the MAC , but eventually I gave up. Without a visible button to click the extension/add-on is unusable. Where I could use it (PC) it appeared to be fabulous. Very upsetting
