([Click here for the Chromium 5 | issue](http://code.google.com/p/chromium/issues/detail?id=67063) and [here for 6 | more info on the 7 | feature](http://techdows.com/2011/12/google-chrome-now-has-built-in-user-agent-switcher.html).) 8 | This renders the dedicated user-agent switching extension obsolete, but the 9 | approach outlined here may still be relevant in the context of a larger 10 | extension. 11 | 12 | Chrome User-Agent Modifier Extension 13 | ==================================== 14 | 15 | Allows you to re-set the "User-Agent" string in Chrome's HTTP request headers. 16 | 17 | Installation Instructions 18 | ------------------------- 19 | 20 | **Download the Extension.** You can get the latest version of the [extension 21 | here](https://raw.github.com/jugglinmike/chrome-user-agent/master/chrome-user-agent.crx) 22 | (of course, you'll need [Google Chrome](http://www.google.com/chrome) installed 23 | first).

24 | 25 | **Install the Application.** Drag the extension file (it is named 26 | 'chrome-ua-modifier.crx' by default) into a Chrome browser window.

27 | 28 | How to Run 29 | ---------- 30 | 31 | **Changing Your User-Agent.** The extension options can be accessed either by 32 | selecting "Options" under the extension's entry on chrome://extensions or clicking on the 34 | extension's logo (

) next to Chrome's omnibox. Select 35 | any entry from the device list, and all future HTTP requests will be sent with 36 | the user-agent string displayed in the text area. Select "default" to use your 37 | default user-agent string. 38 | 39 | **Adding/Modifying "Devices".** Click "Add a Device" to create a new device--be 40 | sure to type a device name in the text area that appears. (You can double-click 41 | any device to change its name.) If you want to change the User-Agent string 42 | associated with any device, select it from the list and modify the text in the 43 | "Current User-Agent" text area. (I have found this page on zytrax.com to be a great resource for valid 46 | user-agent strings.) 47 | 48 | **Deleting "Devices".** If you no longer need a saved device, simply 49 | double-click on its entry in the list and clear the text area. 50 | -------------------------------------------------------------------------------- /src/json2.js: -------------------------------------------------------------------------------- 1 | var JSON;if(!JSON){JSON={};} 2 | (function(){"use strict";function f(n){return n<10?'0'+n:n;} 3 | if(typeof Date.prototype.toJSON!=='function'){Date.prototype.toJSON=function(key){return isFinite(this.valueOf())?this.getUTCFullYear()+'-'+ 4 | f(this.getUTCMonth()+1)+'-'+ 5 | f(this.getUTCDate())+'T'+ 6 | f(this.getUTCHours())+':'+ 7 | f(this.getUTCMinutes())+':'+ 8 | f(this.getUTCSeconds())+'Z':null;};String.prototype.toJSON=Number.prototype.toJSON=Boolean.prototype.toJSON=function(key){return this.valueOf();};} 9 | var cx=/[\u0000\u00ad\u0600-\u0604\u070f\u17b4\u17b5\u200c-\u200f\u2028-\u202f\u2060-\u206f\ufeff\ufff0-\uffff]/g,escapable=/[\\\"\x00-\x1f\x7f-\x9f\u00ad\u0600-\u0604\u070f\u17b4\u17b5\u200c-\u200f\u2028-\u202f\u2060-\u206f\ufeff\ufff0-\uffff]/g,gap,indent,meta={'\b':'\\b','\t':'\\t','\n':'\\n','\f':'\\f','\r':'\\r','"':'\\"','\\':'\\\\'},rep;function quote(string){escapable.lastIndex=0;return escapable.test(string)?'"'+string.replace(escapable,function(a){var c=meta[a];return typeof c==='string'?c:'\\u'+('0000'+a.charCodeAt(0).toString(16)).slice(-4);})+'"':'"'+string+'"';} 10 | function str(key,holder){var i,k,v,length,mind=gap,partial,value=holder[key];if(value&&typeof value==='object'&&typeof value.toJSON==='function'){value=value.toJSON(key);} 11 | if(typeof rep==='function'){value=rep.call(holder,key,value);} 12 | switch(typeof value){case'string':return quote(value);case'number':return isFinite(value)?String(value):'null';case'boolean':case'null':return String(value);case'object':if(!value){return'null';} 13 | gap+=indent;partial=[];if(Object.prototype.toString.apply(value)==='[object Array]'){length=value.length;for(i=0;i 1000 ) { 61 | this.lastClicked = now; 62 | return; 63 | } 64 | this.lastClicked = 0; 65 | var deviceID = event.target.getAttribute('for').match(/device_(.+)_button/i)[1], 66 | deviceName = event.target.innerHTML, 67 | textField = dom.createTextField(deviceID, deviceName); 68 | event.target.parentNode.replaceChild(textField, event.target); 69 | textField.focus(); 70 | }, 71 | nameBlur: function( event ) { 72 | var oldDeviceID, 73 | newDeviceID, 74 | deviceName = event.target.value; 75 | 76 | newDeviceID = deviceName.replace(/ /gi, '_').toLowerCase(); 77 | oldDeviceID = event.target.id.match(/device_(.+)_textfield/i); 78 | oldDeviceID = oldDeviceID && oldDeviceID[1]; 79 | 80 | 81 | if( oldDeviceID && newDeviceID ) { 82 | // Replace text field with label 83 | var li = document.createElement('li'), 84 | radio = dom.createRadioButton(newDeviceID), 85 | label = dom.createLabel(newDeviceID, deviceName); 86 | li.setAttribute('id', 'device_' +newDeviceID+ '_li'); 87 | li.appendChild(radio); 88 | li.appendChild(label); 89 | 90 | event.target.parentNode.parentNode.replaceChild(li, event.target.parentNode); 91 | devices[newDeviceID] = devices[oldDeviceID]; 92 | devices[newDeviceID].name = deviceName; 93 | if( oldDeviceID !== newDeviceID ) { 94 | delete devices[oldDeviceID]; 95 | } 96 | localStorage['devices'] = JSON.stringify(devices); 97 | } else { 98 | // Delete oldDeviceID's list element 99 | deleteDevice(oldDeviceID); 100 | if( newDeviceID ) { 101 | // Insert new element 102 | while( devices[newDeviceID] ) { 103 | newDeviceID += '-'; 104 | } 105 | devices[newDeviceID] = { 106 | name: deviceName, 107 | ua: current_ua_field.value 108 | }; 109 | addDeviceElement(newDeviceID, deviceName); 110 | localStorage['devices'] = JSON.stringify(devices); 111 | } 112 | } 113 | }, 114 | deviceButtonClick: function(event) { 115 | var regexp = new RegExp('(default' + (deviceListStr ?
