>>51044167Waterfox and cyberfox are literally rebranded firefox for retards like you.
Palemoon removes the botnet (DRM, webrtc, hello, pocket, ads), removes legacy support (windows XP and prior, accessibility features), has a series of performance improving patches, adds additional HTML5 support (such as date and time forms which firefox still doesn't support to this date), adds customization (where you want the tabs, whether or not you want the status bar and what it should display, etc.), removes general cancer like australis, disables security flaws like pdfjs, and more.
Icecat only removes nonfree shit like DRM and possibly pocket, and has addons like librejs enabled by default.
