title: Jquery browser version detection
body: <p>OS: Windows XP</p>
  
  <p>Browser: Firefox 5.0 (use it and update it from 3.5)</p>
  
  <p>Jquery: 1.6.2(from cdn <a href="http://code.jquery.com/jquery.min.js" rel="nofollow">http://code.jquery.com/jquery.min.js</a>)</p>
  
  <p>In my jquery script I use browser detection feature and it returns me 1.9.2.15 version, but here : <a href="http://en.wikipedia.org/wiki/Mozilla_Firefox_5#Version_5.0" rel="nofollow">http://en.wikipedia.org/wiki/Mozilla_Firefox_5#Version_5.0</a> there is no such version! Also I have problem because my script thinks that it work with Firefox 3.6 instead of 5.0.</p>
  
  <p>Is this firefox's user agent bug or jquery?</p>
  
  <p>Thanks.</p>
  
  <p>UPD: it seems this is firefox bug, checked with <a href="http://developer.yahoo.com/yui/examples/yahoo/yahoo_ua_detection_clean.html" rel="nofollow">http://developer.yahoo.com/yui/examples/yahoo/yahoo_ua_detection_clean.html</a> and it created object YAHOO.env.ua with value <strong>gecko :1.92</strong> !!!</p>
  
  <p>UPD2: Checked my browser with <a href="http://davecardwell.co.uk/javascript/jquery/plugins/jquery-browserdetect/" rel="nofollow">http://davecardwell.co.uk/javascript/jquery/plugins/jquery-browserdetect/</a> it detected <strong><em>You are using version: 3.6.15 (3.6)</em></strong></p>
  
  <p>UPD3: Tested on Windows 7 with clean firefox - UA version = 5.0</p>

  <p>UPD5: Sorry everyone, found in "about:config" string replacement. It was old plugin bug.Thank to firefox developers for answer. Question closed. I will not remove this question so everyone will know to check "about:config" before panic :)</p>
