Firefox Accounts Referrals¶
Marketing pages often promote the creation of a Firefox Account (FxA) as a common call to action (CTA). This is typically accomplished using either a signup form, or a prominent link/button. Other products such as Mozilla VPN use similar Firefox Account auth flows to manage subscriptions. To accomplish these tasks, bedrock templates can take advantage of a series of Python helpers which can be used to standardize product referrals, and make supporting these auth flows easier.
Note
The helpers below can typically be shown to all browsers, but some also feature logic specific to desktop Firefox, such as signing users into Sync.
Firefox Account Signup Form¶
Use the fxa_email_form
macro to display a Firefox Account signup form on a page.
Usage¶
To use the form in a Jinja template, first import the fxa_email_form
macro:
{% from "macros.html" import fxa_email_form with context %}
The form can then be invoked using:
{{ fxa_email_form(entrypoint='mozilla.org-firefox-accounts') }}
The macro’s respective JavaScript and CSS dependencies should also be imported in the page:
Javascript:
import FxaForm from './path/to/fxa-form.es6.js';
FxaForm.init();
The above JS is also available as a pre-compiled bundle, which can be included directly in a template:
{{ js_bundle('fxa_form') }}
CSS:
@import '../path/to/fxa-form';
The JavaScript files will automatically handle things such as adding metrics parameters for Firefox desktop browsers. The CSS file contains some default styling for the signup form.
Configuration¶
The signup form macro accepts the following parameters (* indicates a required parameter)

value to the macro. For example,utm_campaign='trailhead'
would result in a value oftrailhead-fxa-embedded-form

Tracking Same-Site Links for Mozilla VPN¶
Often we promote Mozilla VPN on different pages via the use of same-site referral
links to the product landing page. For example, we display a “Get Mozilla VPN”
button in the main navigation that links to the /products/vpn/
landing page.
In scenarios such as this we want to understand how many people click the link in the
navigation and go on to signup / subscribe to VPN. To achieve this, we have some
additional logic in fxa-utm-referral.js
that will check for a specific cookie
that gets set when someone clicks a specific referral link.
To create a Mozilla VPN referral link, you can use the vpn_product_referral_link
helper:
{{ vpn_product_referral_link(
referral_id='navigation',
link_text='Get Mozilla VPN',
class_name='mzp-t-secondary mzp-t-md',
page_anchor='#pricing',
optional_attributes= {
'data-cta-text' : 'Get Mozilla VPN',
'data-cta-type' : 'button',
'data-cta-position' : 'navigation',
}
) }}
The helper supports the following parameters:
Parameter name |
Definition |
Format |
Example |
---|---|---|---|
referral_id* |
The ID for the referring page / component. This serves as a value for ‘utm_campaign’. |
String |
‘navigation’ |
link_text* |
The link copy to be used in the call to action. |
Localizable string |
‘Get Mozilla VPN’ |
class_name |
A class name to be applied to the link (typically for styling with CSS). |
String of one or more class names |
‘mzp-t-secondary mzp-t-md’ |
page_anchor |
An optional page anchor for the link destination. |
String |
‘#pricing’ |
optional_attributes |
An dictionary of key value pairs containing additional data attributes to include in the button. |
Dictionary |
{‘data-cta-text’: ‘Get Mozilla VPN’, ‘data-cta-type’: ‘button’, ‘data-cta-position’: ‘navigation’} |
When someone clicks the link a cookie gets set with a 1 hour expiry. The
fxa-utm-referral.js
script will then check for the existence of this
cookie on page load and update the product landing page subscription links
with utm parameters that attribute where the click came from.
For example, a referral cookie with the ID navigation
would result
in the following utm parameters being set:
utm_source=www.mozilla.org
.
utm_campaign=navigation
.
utm_medium=referral
.
Note
The above attribution will only be applied if there are not already utm parameters on the product landing page URL. We will also respect privacy and only set the cookie if DNT is disabled.
Link Metrics¶
When using any of the FxA or VPN helpers that link directly to FxA,
a templates’s respective JavaScript bundle should also import and
initialize the FxaProductButton
script.
import FxaProductButton from './path/to/fxa-product-button.es6.js';
FxaProductButton.init();
The above JS is also available as a pre-compiled bundle, which can be included directly in a template:
{{ js_bundle('fxa_product_button') }}
This script automatically adds metrics parameters to the button href
:
deviceId
flowId
flowBeginTime
These are values are fetched from an API endpoint, and are instered back into the destination link along with the other standard referral parameters.
Important
Requests to metrics API endpoints should only be made when an associated CTA is
visibly displayed on a page. For example, if a page contains both a Firefox Accounts
signup form and a Firefox Monitor button, but only one CTA is displayed at any one
time, then only the metrics request associated with that CTA should occur. For links
generated using the fxa_link_fragment
helper, you will also need to manually
add a CSS class of js-fxa-product-button
to trigger the script.
Tracking External Referrers¶
If the URL of a bedrock page contains existing UTM parameters on page load, bedrock will
attempt to automatically use those values to replace the inline UTM parameters in Firefox Account and Mozilla
VPN links. This is handled using a client side script in the
site common bundle which can be found in /media/js/base/fxa-utm-referral.js
.
The behavior is as follows:
UTM paramters will only be replaced if the page URL contains both a valid
utm_source
andutm_campaign
parameter. All other UTM parameters are considered optional, but will still be passed as long as the required parameters exist.If the above criteria is satisfied, then UTM parameters on FxA links will be replaced in their entirety with the UTM parameters from the page URL. This is to avoid mixing referral data from different campaigns.
Important
Links generated by the FxA button helpers will automatically be covered by this
script. For links generated using the fxa_link_fragment
helper, you will
need to manually add a CSS class of js-fxa-cta-link
to trigger the behavior.
URL Parameter Conventions¶
When choosing URL parameter values, the following conventions help to support uniformity in code and predictability in retroactive analysis.
Use lower case characters in parameter values.
Separate words in parameter values with hyphens.
Follow parameter naming patterns established in previous iterations of a page.
Firefox Sync and UITour¶
Since Firefox 80 the FxA link and email form macros use UITour to show the Firefox Accounts page and log the browser into Sync or an Account. For non-Firefox browsers or if UITour is not available, the flow uses normal links that allow users to log into FxA as a website only without connecting the Firefox Desktop client. This UITour flow allows the Firefox browser to determine the correct FxA server and authentication flow (this includes handling the China Repack build of Firefox). This transition was introduced to later migrate Firefox Desktop to an OAuth based client authentication flow.
The script that handles this logic is /media/js/base/fxa-link.js
, and will automatically apply
to any link with a js-fxa-cta-link
class name. The current code automatically detects if you are in the
supported browser for this flow and updates links to drive them through the UITour API. The UITour
showFirefoxAccounts
action supports flow id parameters, UTM parameters and the email data field.
Testing Signup Flows¶
Testing the Firefox Account signup flows on a non-production environment requires some additional configuration.
Configuring bedrock:
Set the following in your local .env
file:
FXA_ENDPOINT=https://accounts.stage.mozaws.net/
For Mozilla VPN links you can also set:
VPN_ENDPOINT=https://stage-vpn.guardian.nonprod.cloudops.mozgcp.net/
VPN_SUBSCRIPTION_URL=https://accounts.stage.mozaws.net/
Note
The above values for staging are already set by default when Dev=True
,
which will also apply to demo servers. You may only need to configure
your .env
file if you wish to change a setting to something else.
