Default Language problems
Search results keep coming up in Russian. I have cleared the cache, the history, for all time, installed the language add-on, and even reinstalled Firefox. Still coming up in Russian.

What language is Firefox in? What country are you in? Do you use a VPN? And what search engine do you use?

The "Intl" section in your troubleshooting information only shows "en-US", so I think there are two possibilities. One if the setting of the preferred languages in "Options/Preferences -> General".
Another possibility is that you use a VPN or proxy that locates you in a different country.
Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Safe Mode start window

You can check the connection settings.
- Options/Preferences -> General -> Network: Connection -> Settings
If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.
