Exporting Your Browser Cookies on a Mac (Chrome, Firefox, Safari)
Published: April 12, 2018
Recently, for some research I’ve been doing I’ve had the desire to get an export of all my browser cookies. I wound up taking a look at how to do this the three browsers I use, Chrome, Firefox and Safari. In this post I’ll document my findings.

Chrome stores your cookies in your profile folder within
~/Library/Application Support/Google/Chrome. For me, there’s a folder
Profile 1 within that directory with a file named
Cookies. That file is actually an sqlite database with all your cookies. They are stored in a table named
$ pwd /Users/maxchadwick/Library/Application Support/Google/Chrome/Profile 1 $ sqlite3 SQLite version 3.19.3 2017-06-27 16:48:08 Enter ".help" for usage hints. Connected to a transient in-memory database. Use ".open FILENAME" to reopen on a persistent database. sqlite> .open Cookies sqlite> .schema --indent cookies CREATE TABLE cookies( creation_utc INTEGER NOT NULL UNIQUE PRIMARY KEY, host_key TEXT NOT NULL, name TEXT NOT NULL, value TEXT NOT NULL, path TEXT NOT NULL, expires_utc INTEGER NOT NULL, secure INTEGER NOT NULL, httponly INTEGER NOT NULL, last_access_utc INTEGER NOT NULL, has_expires INTEGER NOT NULL DEFAULT 1, persistent INTEGER NOT NULL DEFAULT 1, priority INTEGER NOT NULL DEFAULT 1, encrypted_value BLOB DEFAULT '', firstpartyonly INTEGER NOT NULL DEFAULT 0 ); CREATE INDEX domain ON cookies(host_key); CREATE INDEX is_transient ON cookies(persistent) where persistent != 1; sqlite>
The cookie values are actually stored in the
Fortunately, this python script can be used to decrypt them.
You will need to supply it with your Chrome Safe Storage password. Per the“Decrypt Chrome Cookies with Python” blog post, the following command can be used to pull that…
security find-generic-password -w -s "Chrome Safe Storage"
Similar to Chrome, Firefox uses a sqlite database for storing your cookies. The good news is that they’re not encrypted, which simplifies the process of extracting them.
To find the path, click the “Troubleshooting Information” menu item under the Help menu. Then, click the “Show in Finder” button next to “Profile Folder”.
In that folder you’ll see a file named
The cookies are stored in the
moz_cookies table, with the values in the
$ pwd /Users/maxchadwick/Library/Application Support/Firefox/Profiles/56qqyyl6.default $ sqlite3 SQLite version 3.19.3 2017-06-27 16:48:08 Enter ".help" for usage hints. Connected to a transient in-memory database. Use ".open FILENAME" to reopen on a persistent database. sqlite> .open cookies.sqlite sqlite> .schema --indent moz_cookies CREATE TABLE IF NOT EXISTS "moz_cookies"( id INTEGER PRIMARY KEY, baseDomain TEXT, originAttributes TEXT NOT NULL DEFAULT '', name TEXT, value TEXT, host TEXT, path TEXT, expiry INTEGER, lastAccessed INTEGER, creationTime INTEGER, isSecure INTEGER, isHttpOnly INTEGER, inBrowserElement INTEGER DEFAULT 0, sameSite INTEGER, CONSTRAINT moz_uniqueid UNIQUE(name, host, path, originAttributes) ); CREATE INDEX moz_basedomain ON moz_cookies(baseDomain, originAttributes);
Safari stores it’s cookies in
~/Library/Cookies. There you’ll find a file named
The data is in binary format, but again, there’s an excellent python script which can be used for parsing.
