This extension can switch the user agent of a browser. and it allows you to find all HTTP URLs.

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 extension supports Chrome 18 and later. *Enable,disable switcher *Add,edit User Agent list *Filters to apply *URL pattern to apply *View URL sniffer log (type,method,URL,original HTTP headers..) *Export/Import settings *Various options

When active using the updated list of user agents i get website errors "Your browser is out of date! Update your browser to view this website correctly." Clearly, this is using a very outdated list of user agents! Shame on the developer for halfassing it

pros: rich flexible configurations, can use regex matching. cons: not supporting navigator.userAgent and User-Agent Client Hints (sec-ch-ua headers) adjustment which "User Agent Switcher and Manager" can do. overall good extension.
