For regular themes:
- To change the product text on the browser tab, in Classic, go to Administration > UI Themes
- Find the one you are using and look for this section #ppm_header_product
- You can edit, for example:
/* The product name itself */
#ppm_header_product span:before, #ppm_header_product_small span:before {
content: "My Company DEV Environment";
}

This is DE64975: Cannot update HTML title for the Product name on the browser tab when using Phoenix UI Theme, fixed in 16.0.3
