Well, I finally managed to uninstall and reinstall Firefox. I went to the Firefox program folder and saw an uninstall program there - it managed to do what the Windows uninstaller couldn't. And I was able to reinstall without incident. So I am back to browsing in a popup-free zone. Hurrah!

In other news, my students have sailed into the doldrums, apparently. All week, the energy level in class has been bottoming out. As I just explained to a colleague, I didn't realize that Spring Break meant "Break in concentration" and "Break in stride" and "Break in momentum" . . . but they definitely seem to have punched out, many of them. The colleague answered, "Wait until it gets warm!" Luckily, only five more weeks of classes and then it's portfolio time. With any luck I, myself, will be able to maintain concentration, stride, momentum that long . . .
