A little Firefox Extension that provides a one-click toggle to spoof as Chrome in Firefox - or, in other words, to put on the Chrome Mask. There are a lot of generic "User Agent spoof" extensions. However, this extension does a few things differently:
Instead of overriding the User Agent string on all sites, this extension allows you to only look like Chrome on specific sites.
Unlike some extensions with outdated version numbers and UA strings, this extension automatically updates the Chrome version it pretends to be. It does that by querying a simple API every 24 hours.
You don't have to pick the correct Operating System manually; this extension does it for you.
This extension also shims a few additional JavaScript attributes, like navigator.vendor or the global chrome object, to pass common browser checks. Starting with Version 9, the extension also shims some basic Client Hints data: the navigator.userAgentData.{brands,mobile,platform} properties; plus the sec-ch-ua, sec-ch-ua-mobile, and sec-ch-ua-mobile headers.
