I can connect to the internet with the Opera Browswer. However, Firefox suddenly won't let me connect. So, I also tried Google Chrome and it will not allow me to connect.

Firefox had been working fine all day. This same problem happened a few weeks ago and I couldn't figure it out. So, I uninstalled Firefox and re-installed it. It worked fine after that. I tried that route again tonight, but no luck.

I have no clue why this is happening. I'm obviously online via Opera right now as I'm submitting this thread.

Thoughts?
