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)

great app!!!
it works perfectly, but it deleted all my extensions for some reason
Works perfectly. However, for those of us who didn't notice the new button, maybe a little "getting started" guide would be nice :-)
Sorry, a pretty user interface begging for money doesn't impress me.
「現在のタブにだけ適用します」というチェックが再起動するたびに外れるため、クロームの設定を「前回のタブを開く」にしていると各タブの表示を手動で直さなければならない。 特に携帯用サイトに自動で転送される類のページの場合は非常に面倒くさい。 （追記）削除したところDefaultがiPhone4で固定され、どんな方法を使っても直せなくなった。再インストールしてIEなどに設定することでPCとしてサイトを見ることが出来るようになったが、chromeとして使用することは二度とできない模様。
User Agent Switcher for Chrome を使っていましたが，何故か動作しなくなったので，こちらに乗り換えました。 多機能で簡単に使えるのがいいですね。
The fact that I can write patterns to match individual websites! AWESUM

I like it. Good
