Created January 7, 2018 21:46
Handy scripts for making screenshots in tor browser. To use, paste in browser console. Then entergrabImage("image-dir", "imagestem", false);
let locales = ["ar", "de", /*"en-US",*/ "es-ES", "fa", "fr", "ja", "it",
"ko", "nl", "pl", "pt-BR", /*"ru",*/ "tr", "vi", "zh-CN"];
let listenOnce = (element, event, useCapture) => {
return new Promise(function (resolve, reject) {
let onEvent = function (ev) {
element.removeEventListener(event, onEvent, useCapture);
resolve(ev);
};
element.addEventListener(event, onEvent, useCapture);

Building DieHarder allocator on Debian

Here's what worked for me.

Building dieharder:

git clone --recursive https://github.com/emeryberger/DieHard
cd DieHard/src
make linux-gcc-x86-64 TARGET=libdieharder

Then I needed to add the following to my Firefox .mozconfig:

@arthuredelstein
arthuredelstein / firefox with libdieharder.so
Last active November 30, 2016 09:20
I built the latest mozilla-central, https://github.com/mozilla/gecko-dev/commit/ef3cede9a5
using a .mozconfig with
`
ac_add_options --disable-jemalloc
ac_add_options --disable-replace-malloc
`
and then ran the firefox at obj.../dist/bin with
`
LD_PRELOAD=/home/arthur/DieHard/src/libdieharder.so ./firefox
`
