Chrome Mask

Makes Firefox wear a mask to look like Chrome to websites that otherwise won't work.
What is Chrome Mask?
"Chrome Mask" is a Firefox extension that allows users to selectively spoof as Chrome on specific websites. With a one-click toggle, it automatically updates the Chrome User Agent string every 24 hours and adjusts for the correct Operating System. Additionally, it shims JavaScript attributes like `navigator.vendor` and the `chrome` object to bypass common browser checks, enhancing compatibility while using Firefox.

Add-on summary

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  • Unlike some extensions with outdated version numbers and UA strings, this extension automatically updates the Chrome version it pretends to be.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.

The fact that it refers to the process as "wearing a mask" makes it 100x better lol
