This tutorial shows you how to fix a frozen browser. One way to fix these pages when it happens to you is to go to the tools tab, and click on clear recent history. When the window opens it will ask how much you want to delete. Select everything. Now sometimes when you are using a browser it will not minimize or maximize and you can not close out of it. When this happens you just have to hit ctrl, alt, delete and open the task manager. Click on the program that says Firefox, then just hit end task and reopen the browser.
