Cons
Con OSX only
Apple dropped Windows support after Safari 5.
Con Does NOT block Ads
Doesn't block ads, unlike browsers like Brave and Vivaldi.
Con Poor support for new web technologies
Safari usually takes its time when it comes to adopting new and useful web technologies meaning that the user gets an inferior experience compared to other modern browsers.
Con Proprietary
While Safari er is currently available gratis (without monetary charge) on Mac OS X, it is currently not libre (meaning that it does not allow users to view the source code used to create, to modify that code, or to redistribute modifications) and is therefore neither free nor open-source software.
Con Outdated Rendering engine
All other browsers and toolkits (Qt/GTK) have shifted to Googles Blink-fork of KHTML/Webkit so Apple is currently the only main contributor left.
Con Terrible support for open source formats like .VP9 or .ogg
Apple does not support open source formats. Instead, they use H.264 and H.265.
Con Even on OSX not the best Experience
Video controls are bad esp. on youtube. Only few browser extensions.
Con External Rendering Engine
It uses the Qt Web Engine from your local Qt installation which is usually not often updated.
Con No support for addons
Con Under GNU GPL
It is licensed under GPL which is less permissive than other opensource licenses like BSD or MIT.
