i see you have there a messy source.list hardly could call it fresh install

let's see, first problem:
- you have there 3 PPA's: damnvid, mozillateam and mozilla security;
- have you already tried to disable them and then update (just to check if they are the problem?)
- because you know, this is debian and, unless you have a very strong reason to use an ubuntu pkg, it is not advisable (it will sooner than later) - and from those PPA's and i can't think of a good reason to use them and break your system: one is a video d/w (and relies on ffmpeg - probably a v. incompatible with the one shipped with lmde) the other 2 PPA are for FF (oh please! if v.9 is not good enough for you- available in your repos- get the v. you want from here http://mozilla.debian.net/ at least is a proper debian channel)
