The problem: Firefox was ignoring my location bar (the text area at the top that you can type a URL in, and when you hit enter, it'll load up.) I could type in it, but pressing enter didn't do anything, and changing tabs didn't change it to the new location.
The solution: (from helpful advice here): I uninstalled two add-ons: BlogRovr and Web Developer, and after the restart, it worked fine. I don't know which of those was at fault, but I don't care now. :)
[Side note: for diagnostic purposes, I did like the advice at the link said and made a clean profile, and found the location bar worked fine there, which pointed the finger at the add-ons.]
