Prevent Chrome's Google Search from defaulting to the local language / Make English Chrome's Default Langauge

Problem: You're in another country and every time you search for something in Chrome, your Google results are shown in another language (and you want them in English).

Solution:

Settings → Manage Search Engines 

Make ANY other search engine the Default

Click on it to edit the address and insert http://www.google.com/search?q=%s

Click "Done"

Remove Bing from Firefox

Problem: You have Firefox, but you hate Bing and want to remove it.  When you type search words into the address bar, it always redirects to Bing (instead of Google).

Solution: Type "about.config" in the address bar → Enter → I'll be careful, I promise! → Type "keyword.URL" in search box → Enter → R click → Reset
