HTTPS Everywhere

Getting Started

Get the packages you need and install a git hook to run tests before push:

bash install-dev-dependencies.sh

Run all the tests:

bash test.sh

Run the latest code and rulesets in a standalone Firefox profile:

bash test/firefox.sh --justrun

Run the latest code and rulesets in a standalone Chromium profile:

bash test/chromium.sh --justrun

Build the Firefox extension as a .xpi package:

bash makexpi.sh

Build the Chromium extension as a .crx package:

bash makecrx.sh

Both of the build commands store their output under pkg/.

Precommit Testing

One can run the available test suites automatically by enabling the precommit hook provided with:

ln -s ../../hooks/precommit .git/hooks/pre-commit

Source Tree

This is the source tree for HTTPS Everywhere for Firefox and Chrome.

Important directories you might want to know about

src/                      The Firefox source
chromium/                 The Chromium/Chrome source
                          (not to be confused with Firefox browser "chrome" or UI)
src/components            |
src/chrome/content        | Firefox JavaScript and XUL code
src/chrome/content/code   |
src/chrome/content/rules  The rulesets live here
test/                     The tests live here

Hacking on the Source Code

The current stable release series is 5.2. The maintainers release new versions off the current master branch about every two weeks.

To submit changes, either use pull requests on GitHub or email patches to https-everywhere-rulesets@lists.eff.org (rulesets) or https-everywhere@lists.eff.org (code).

Writing rulesets

HTTPS Everywhere consists of a large number of rules for switching sites from HTTP to HTTPS. You can read more about how to write these rules here: https://www.eff.org/https-everywhere/rulesets

If you want to create new rules to submit to us, we expect them to be in the src/chrome/content/rules directory. That directory also contains a useful script, make-trivial-rule, to create a simple rule for a specified domain. There is also a script called trivial-validate.py, to check all the pending rules for several common errors and oversights. For example, if you wanted to make a rule for the example.com domain, you could run

bash ./make-trivial-rule example.com

inside the rules directory. This would create Example.com.xml, which you could then take a look at and edit based on your knowledge of any specific URLs at example.com that do or don't work in HTTPS. You should then run

bash test.sh

to make sure that your rule is free of common mistakes.

Writing translations

If you would like to help translate HTTPS Everywhere into your language, you can do that through the Tor Project's Transifex page: https://www.transifex.com/projects/p/torproject/.

Bug trackers and mailing lists

We currently have two bug trackers. The one on GitHub (https://github.com/EFForg/https-everywhere/issues) is recommended because it gets checked more frequently and has a friendlier user interface. The one on trac.torproject.org (https://trac.torproject.org/projects/tor/report/19) has a large backlog of bugs at this point, but it has the advantage of allowing you to post bugs anonymously using the "cypherpunks" / "writecode" account. (Note that you won't see replies unless you put an email address in the CC field.)

We have two publicly-archived mailing lists: the https-everywhere list (https://lists.eff.org/mailman/listinfo/https-everywhere) is for discussing the project as a whole, and the https-everywhere-rulesets list (https://lists.eff.org/mailman/listinfo/https-everywhere-rules) is for discussing the rulesets and their contents, including patches and git pull requests.

Tests

There are some very basic unittests under test/. These are run with

bash test.sh

Please help write more unittests and integration tests!

There are also ruleset tests, which aim to find broken rulesets by actually loading URLs in a browser and watching for Mixed Content Blocking to fire. The easiest way to run ruleset tests is to load a standalone Firefox instance with the tests enabled:

bash test/firefox.sh --justrun

Then click the HTTPS Everywhere icon on the toolbar, and click "Run HTTPS Everywhere Ruleset Tests." When you run the tests, be prepared to let your computer run them for a really long time.
