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)

This is a superb extension EXCEPT that the settings do not sync. That's an absolute must. The entire point of Chrome is the synchronization of everything. Again, though -- a very good extension! Edit: PLEASE make this sync with the account, so that any machine will get the settings for a user. Depending on local machine continuity for cloud-oriented workflow is really retrograde. ;-)
Gave me old tumblr back yus
Doesn't work
awsome for fast browsing in mobile view on pc!!!
Good Job!!
This is the best of the ones that I have tried. The list of User Agent strings is pretty decent, but you can add them and you can specify certain UA's to be used on predefined URL's. For example, I can't use my Chromebook with Outlook Web Access unless I pretend to be Chrome on a Mac.
it's great but import user agents list via xml file feature missed.........
One of the best extension chrome has!!!
Very powerful - just what I was looking for. Additional sniffing capabilities and policy-driven configuration options make this a must-have utility for Chromium (and Chrome ) users.
Perfect extension
