Once you have downloaded and installed this add-on, the new options, Tools > Default User Agent and Tools > Modify Headers should appear in your browser.
To emulate browsing on a mobile device, you need to find the User Agent Profile (UAProf) value of your mobile device, which can be found with a quick search on Google for "user agent" followed by the model of your phone (e.g. see Google results for "user agent ipad"). Alternatively, check out this list of UAProf values.
Once you have located the UA Profile value for the phone you want, enter it into the Modify Header dialog box, and bingo, you will see how it’s like to browse from that device.
For Google Chrome, you can try out the User-Agent Switcher extension.
For a browser-independent desktop application that works on virtually any internet-enabled app, try out Fiddler Web Debugger that lets you modify HTTP requests, among other things.
