URL: https://ca.search.yahoo.com/yhs/errorhandler?hspart=gt&hsimp=yhse-gt&q=http%3A%2F%2Fwww.telus.net%2Fimages%2Fline10&type=808263
Browser / Version: Firefox 41.0
Operating System: Mac OS X 10.10
Problem type: Something else - I'll add details below

Steps to Reproduce

1. Navigate to: https://ca.search.yahoo.com/yhs/errorhandler?hspart=gt&hsimp=yhse-gt&q=http%3A%2F%2Fwww.telus.net%2Fimages%2Fline10&type=808263
2. …

What's happening: This is the link I get redirected to when I click on links from a web search. It's super annoying. Even if I click the back button it just keeps redirecting me to this page and it won't let me leave.

Problem #2: Firefox keeps resetting my URL box to use Yahoo as my search engine, and every day I go into my preferences and change it back to google, and every day it resets itself to Yahoo.
