Hardening the #Firefox Frontend with Content Security Policies

attackanddefense.dev/2025/04/0

Attack & Defense · Hardening the Firefox Frontend with Content Security PoliciesMost of the Firefox User Interface (UI), including the address bar and the tab strip, are implemented using standard web technologies like HTML, CSS and JavaScript plus some additional custom components like XUL. One of the advantages of using web technologies for the front end is that it allows rendering the frontend using the browser engine on all desktop operating systems. However, just like many web applications are susceptible to some form of injection attack (OWASP Top Ten), Firefox’s use of web technologies for the frontend makes it no exception and hence it is vulnerable to injection attacks as well.

@joshg Took a few minutes to type in, but it’s not egregious, the logic is straightforward and can be solved by hand easily. But it’s more instructive this way:

include "alldifferent.mzn";

% Two lists of ints between 1 and 5, both inclusive
% One we'll use for the indices of the matrix cell coordinates, and the other for cell values.
set of int: COORD = 1..5;
set of int: VALUE = 1..5;

% Define a matrix, which is a 2-dimensional array with indices for its cells
% defined by COORD, so between 1 and 5, where each matrix cell
% takes any value of those defined in the list VALUE:
array[COORD,COORD] of var VALUE: v;

% All different in rows: the 'j' coordinate advances in the column
constraint forall(i,j in v)(
alldifferent([v[i,j] | j in VALUE]));

% All different in columns: the 'i' coordinate advances in the row
constraint forall(i,j in v)(
alldifferent([v[i,j] | i in VALUE]));

% All the groups of cells that add up to 10,
% using either sums (+ sign) or multiplications (* sign)
constraint v[1,1] + v[1,2] + v[1,3] + v[1,4] = 10;
constraint v[1,5] + v[2,5] + v[3,5] = 10;
constraint v[2,1] + v[2,2] + v[3,1] = 10;
constraint v[2,3] * v[2,4] * v[3,4] = 10;
constraint v[3,2] + v[3,3] + v[4,2] = 10;
constraint v[4,1] + v[5,1] + v[5,2] = 10;
constraint v[4,3] + v[5,3] + v[5,4] + v[5,5] = 10;
constraint v[4,4] * v[4,5] = 10;

solve satisfy;

5 by 5 grid with rules on groups of cells that add up to 10 or multiply to 10.

Son: can you help me with this math homework. Is like a sudoku but with other constraints.

Me: sure, let's write this constraint satisfaction problem as a minizinc program ...

Son: cool, but can you teach me to solve it without programming.

Me: what's the point of that.

I am not sure what math skill this is meant to teach other than developing frustration for "math". Are the teachers secretly hoping kids will be learning to formalize CSPs early in life? Because that's what they'll get.

💖 Furra ✨

Behold!! The Croco-Bat (?) 🐊🦇

I finally made my fursona! A mix between 2 characters [A crocodile and a bat] that I used in the past to repesent myself but never felt like those were fursonas of mine at all... until I fuse them ✨

I will continue drawing myself as a human bc I like also how I draw myself in that way, but sometimes I will also draw myself as a furry~ Mostly when I want to interact with my furry OCs (?)

I had so much fun designing her. I even broke some personal rules of design while drawing her and it felt so good~ I hope you guys like it!!!! 💖

- Drawing Type: Normal Style / Colored Sketch / Fullbody - [ 1 ] Character/s: * Furry / Crocodile + Bat / Female - Background: Flat Color - Description: Design of my fursona! She's a mix between a crocodile and a bat. Her design is mostly soft pink with some hadr pink details in zones like the tail, wings and ears. On the wings and the hair the colors change to a deep blue, and have purple eyes, but most of the time she have a "toony" look that doesn't show that detail. The anatomy is mostly of a bat, but she have the crocodile elements like in her tail and the stomach, as well of having claws like a reptile

🔄 Magnus 🔄

[12-04-2022 / 13-04-2022]

Another of my old OCs! This is Magnus, he's part of an universe of angels and demons, but he's in the mortal side~

As a fun fact, he have an official ship with Nia, the OC of my friend happyoreof9 @ FurAffinity !

- Drawing Type: Normal Style / Cell Shading / Fullbody - [ 1 ] Character/s: * Furry / Male / Deer - Background: Flat Color - Description: Drawing of my OC Magnus. He's a deer with white fur and some soft green details, as well of having green hair with a more lighter tone of green on his hair tips. His antlers are small and "droopy", but he makes up for it with his muscles.

Dovedale Design Work (CKTC. 2023, recolour 2025)
I've been trying to find a colour comp that will work with Dovedale and I think the yellow-green fade is the extra something his design needed. (The base is from 2023)

I can't let Phaelon hoard all the luminous prettiness in plot.
