For some Google search queries executed from the Firefox search bar, or manually by typing in the URL, I get a ''302 Moved'' page. I did a quick virus scan, have checked the hosts file and the plugins and add-ons that are installed in Firefox. Nothing is out of the ordinary. What could be the problem?

These URLs (and any URL with google.com, empty and firefox-a in them) show me a 302 Moved page:

Whereas these URLs work fine:

By default Google redirects my queries to their .nl website, and uses HTTPS. I am currently executing a full system virus scan using Security Essentials. My Firefox plugins were up-to-date. No unfamiliar Firefox plugins or add-ons found. Restarting Firefox did not solve the issue. The issue does not occur in Internet Explorer. The hosts file did not contain any unfamiliar entries.

After restarting Firefox with all add-ons and plugins disabled, the issue went away. By enabling each add-on and testing it, I found that DoNotTrack+ is the culprit.

However, I don't know how to solve it. I cannot add google.com to the whitelist as there are no trackers to block. And even so, I am not sure that whitelisting Google would solve the problem.

You should ask a follow-up question about making Google play nice with DoNotTrack+ if it has not already been asked here :) I think you can also mark your own answer as the answer for the question. –  Darth Android Oct 2 '12 at 16:33
Was having the same issue with either disconnect or ghostery - didn't have the time to isolate which –  eggonlegs Aug 19 '13 at 0:24
