Ranked in these QuestionsQuestion Ranking
Pro Extremely fast
Pro Works elegantly in OSX
The rendering of the pages and the browser compatibility with OSX works smoothly, when compared to other browsers. Also you get very high battery life with Safari, when compared to Chrome.
Pro Sleek design
– No distraction stuff like favicons in tabs, all that borders, bevels and embosses in panels like in other browsers, no ugly shaped tabs.
– Neat adress bar.
– Good looking start “show all tabs” screen.
Pro iCloud syncing
Tabs, passwords, bookmarks and, history all sync across devices.
Pro Same rendering engine as Firefox
Iceweasel uses the same rendering engine as Firefox which is one of the fastest browsers around.
Pro External security fixes
In order to work on any system, Firefox Linux libraries contatin copies of all libraries despite what's installed in the system. While Iceweasel uses the system libraries only.
This way, when a certain library gets a security fix you will get that in the next system update without having to wait for Firefox to update their library tree and wait for their next patch to be released.
Con OSX only
Apple dropped Windows support after Safari 5.
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 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 Updates are released a couple of days later
Since Iceweasel needs to wait for Mozilla to release a new update which then has to be merged by the Debian team into Iceweasel, it can take one or two days more for Iceweasel to get updates.
