This extension hooks into any Schedule of Classes page and parses information about the professor from www.ourumd.com. The professor's average GPA, grade histogram, and review score is displayed in line next to each section. You can click on "GPA" or "Reviews" to directly jump to OurUMD's page for that professor.
It only parses the visible sections, so it won't bog down OurUMD's servers too much. Most of the code hasn't been tested too much (remnants of it are from CMSC132) so expect some problems from time to time parsing info.
