Question Ranking
Pros
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.
Pro Naturally well-suited to accessibility tools
Being a text-based browser, Lynx is easy to operate using text-to-speech or Braille tools for visually-impaired users.
Pro Still under active development
Lynx offers surprising compatibility with current WWW standards, including SSL/TLS.
Pro Oldest web-browser still in general use
Lynx was first released in 1992. Using it is one of the best hands-on ways to understand the history of the Web.
Cons
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.
