Stratiform Alternatives
Stratiform is described as 'is the ultimate user friendly customization add-on for Firefox. It puts the power in the average user's hands to customize the browser's look' and is an app in the web browsers category. There are four alternatives to Stratiform for Firefox, Windows, Linux and Mac. The best alternative is ShadowFox, which is both free and Open Source. Other great apps like Stratiform are VivaldiFox, Firefox Themes and Personas Plus.
ShadowFox was inspired by changes made in Firefox 57, which limited the amount addons could customize both the user interface and "protected" web pages.
