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.

I installed it, but I don't see any "browser button" I'm assuming the purpose isn't to merely create a bookmark for Google Scholar... support page does not exist or I would search for help. Using latest Firefox. I use Google Scholar almost every day.

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
