Overview
Product summary
Review the store description, core capabilities, and common use cases.
Most web pages are fully and completely compatible with Chrome.
However, there are some sites that insist upon using a different browser.
So, an extension has been developed for Chrome called the Ultimate User Agent Switcher.
When a web page suggests using a different browser or upgrading the current one,
the Ultimate User Agent Switcher tricks the web site into believing that it is a different browser, often allowing access.
And this extension allows you to find all HTTP URLs. (URL sniffer feature)

it is great and work really well. However, number of user agents of smartphone are very less. Like to see how android 4.0 or 4.1 looks.
funziona davvero rispetto ad altri.
Hi This did get 5 stars, but after the upgrade to chrome 19.0.1084.52 on linux, this extension does not appear to be working!
Does not work. Sites still sniff the browser as Chrome.
Would be 5 if it had Windows Phone 7
Very good user agent switcher. Very easy to use. A plus for that you can add custom user agents
very useful
This is fine if you want to use the presets, however you can't customize user-agents. It appears you can, but the changes aren't actually saved. Also, if you edit a preset, it doesn't actually "stick" either -- and you have no way of selecting it from the drop down anyway. This app also does annoying things like puts ads in the extension itself, and begs you to rate it 5 stars, which is an annoyance.
Awesome.
Love it. Just what I needed, plus a URL sniffer! (I needed that too, eventually)
