When I type a website into the address bar and press enter, nothing happens.
I updated Firefox, and immediately afterward, my address bar seemed to become unresponsive. If I want to navigate to any website, I have to go to my homepage and Google it. I tried restarting, and nothing changed. (I am not very computer literate, so that is about the extent of my troubleshooting abilities.)
Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
Don't make any changes on the Safe mode start window.
