Package: iceweasel

Followup-For: Bug #400858
An ambivalent "me too" note, with details and comments:

24:Description: lightweight web browser based on Mozilla
25- Iceweasel is a redesign of the Mozilla browser component, similar to
26- Galeon, K-Meleon and Camino, but written using the XUL user interface
27: language and designed to be lightweight and cross-platform.
...from that many users might infer IW was light on system
resources, such as memory.

Maybe "light" is a relative term, but 117 megabytes seems
weighty. Yet the 'free' (column #3) RAM figure is less, about
17Megs RAM used.
Compare this to the less powerful 'dillo' loading the same
237K bookmarks page:
free ; dillo .mozilla/firefox/ozucj9pf.default/bookmarks.html & sleep 40s

Hmm, 'dillo' shouldn't be that big. I doubt this measurement is the
right way to do it. Probably it's showing the sizes of various underlying
libraries as well. If that's true, then the 100M figure might be
unfair to 'iceweasel'.
The 'free' figure for 'dillo' suggests it's using about 300K RAM.
Relatively speaking, that still makes 'iceweasel' at 17M much
less light that 'dillo' at 300K -- it uses 56 times as much RAM.
Suggestions for better measurements wanted...
