Wrong user agent

I used K-Meleon 1.1.5 user agent set to spoof IE 6.0 ( 6.0, not 7.0 ). I set proxy for Tor, then went to a website to see what browser website detected. It said I was using Firefox 2.0.0.14. I have Firefox 2.0.0 14 installed on my computer but I was not using Firefox at that time. I had to exit K-Meleon then re-enter for the user agent ( IE 6.0 ) to be correctly detected. Since Firefox 2.0.0.14 is not listed as an option on K-M 1.1.5 user agent selection ( Firefox 2.0.0.8 is ), I wonder why the website said that was the browser being used?

The page did not detect that I used a German K-Meleon 1.1.4. This code only reads out the User Agent string that is sent by default or as the spoofed User Agent. It betrays my German IP. Germans and Russians habitually visit with native speaking browsers grinning smiley So something must be wrong with my User Agent String smiling smiley


Actually AFAIK You can devise a way to find that You are visited by a browser that is driven by a Gecko engine - but not which browser.

Go to Gemal.dk:

This is the give-away that betrays a Gecko with activeX:
ActiveX supported No or unable to detect... (that would be a true IE)
GeckoActiveX supported Yes ( any Gecko that has activeX support / this is the first thing that occured to me - there should be others ). To be fairly save against browser spying You need to switch off JavaScript.

Go here to find out more about Geckos at Gemal.dk:

UserAgent Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)
Gecko Product Yes - version Gecko 20080203
Gecko Vendor Yes - version 1.1.4
Mozilla No or unable to detect...
K-Meleon No or unable to detect...

Tells You that I did the test with an 1.1.4 but even he cannot detect K-Meleon smiling smiley
to tell You would have to keep a list which 1.1.4 of what browser uses that particular Gecko engine.

So You can cleverly devise tests that give away much - if not all.

p. s. Gemal.dk is my standard browser spying page.

p.p.s. It is not good to spoof IEs since they speak another JavaScript dialect then Geckos. Spoofing IE causes JavaScript problems e.g. with Yahoo.mail and other pages. Also web pages assume that You can use IE's native mechanisms especially activeX. And these are not fully supported by the Gecko-ActiveX plugin.

I have tried, and all the strings set are returned identical.

I have tried IE6 by using IE7 and changing by using Custom and replacing the string IE7 by IE6 , because the string handled with 1.1.5 is IE7, and it returns IE6

For me it's ok, but you must know that these strings are sometimes not tested to retrieve the real browser. Javascripts are often used.

@guenter,
@JujuLand,

Thanks for the information. The returning of user agent Firefox 2.0.0.14 when using K-Meleon 1.1.5 has happened only one time. I'm thinking it's one of those 'once in a blue moon' anomalies that happens to computers sometimes. Thanks again.
