Mozilla Firefox is a Free and Open Source web browser developed by the Mozilla Foundation.

It can have many add-ons which give it extra capabilities.

Anonymous Browsing

Mozilla Firefox can be used in anonymous browsing (see The Onion Router). However, it is known that Firefox reveals computer's uptime in TLS (SSL) "Client Hello" packets allowing investigator correlate anonymous and non-anonymous traffic [1].

This bug affects Firefox 2 (all versions) and Firefox 3 Beta3.


Firefox 3 stores the history of visited sites in a file named places.sqlite. This file uses the SQLite database format.

places.sqlite can be found in the following locations:

On Linux


On MacOS-X

/Users/$USER/Library/Application Support/Firefox/Profiles/$PROFILE.default/places.sqlite

On Windows XP

C:\Documents and Settings\%USERNAME%\Application Data\Mozilla\Firefox\Profiles\%PROFILE%.default\places.sqlite

On Windows Vista, 7



The places.sqlite uses the following timestamps.


The visit date and time values in the moz_historyvisits table are in (the number of) microseconds since January 1, 1970 UTC

Some Python code to do the conversion into human readable format:

date_string = datetime.datetime( 1970, 1, 1 )
            + datetime.timedelta( microseconds=timestamp )

Example queries

Some example queries:

To get an overview of the visited sites:

SELECT moz_historyvisits.visit_date, moz_places.url FROM moz_places, moz_historyvisits WHERE = moz_historyvisits.place_id;


Firefox 3 stores the history of downloads sites in a file named downloads.sqlite. This file uses the SQLite database format.

downloads.sqlite can be found in the same location as places.sqlite.
