Features & Capabilities

Most web sites pages don't use the domain name as body class to distinguish from other web sites' pages. That makes web page appearance customization hard in some degree. The reason is that people have to distinguish web sites by specific configuration (by domain name, regex etc).

By adding domain name to body classList, the problem could be solved. Web/UI/UX developers can create customized styl, css scripts to re-design web page appearance easily - they can put all customization script together for different web sites and don't need to care about collision.

For example, after using the add-on, the web page will be changed to add domain name to body class attribute. <body class="mozilla "> <body class="apache">

Then, in styl or css script file, developer can make customization like below: body.mozilla {font-size: 15px} body.apache {font-size: 16px}

Is domain.cls Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

domain.cls requires a few sensitive permissions. Exercise caution before installing.
