Anyone else have problems with Google search when using Fiddler?

[Rafe]

So several times over the past two months I head over to Google.com to do my googling. All is going well until suddenly Google decides that I am a bot and throws a captcha screen in front of me instead of my search results. From then on it's no Google for me no matter how many captchas I enter and no matter which browser I use. I've pretty much just had to do my search via a different search engine, and wait it out until Master Google decides that I am worthy of its service again.

Yesterday it happened again and it occurred to me that I was running Fiddler. After turning Fiddler off and waiting a bit I was able to use Google again. 

Has anyone else experienced this?

Hi, Rafe--

Who's your ISP and how are you connected to the Internet?

You will see this if you used Fiddler to chain to TOR or some upstream shared proxy provider (some geo-located VPNs, for instance) because Google sees a lot of unrelated traffic coming from a single IP address and it freaks out.

It's possible you could see this if you used Fiddler to modify requests in an unusual way (e.g. changing the user-agent string to something crazy or adding X-Forwarded-For headers and the like).

Other than those two things, are no known cases where Fiddler would cause you to see this without making modifications.
