[niky 45]

i suppose this means that it's not iceweasel's fault, but an extension.
however, why does iceweasel 5.0 does not use so much ram, with the same
extensions?? (yes, almost all of them are compatible with both versions. one
or two of them, however, are not compatible with anything above 3.5, i
think. i'm using the addon comatibility reporter to run them.). as i said,
none of them cause trouble in iceweasel 5.0.

PS: i'll give a list of extensions, but have no idea of how to get such a
list in plain text (i have enough of them to not show in a single
screenshot)
