# Targeting attributes
When you create ASRouter messages such as contextual feature recommendations or onboarding cards, you may choose to include **targeting information** with those messages.
Targeting information must be captured in [an expression](./targeting-guide.md) that has access to the following attributes. You may combine and compare any of these attributes as needed.
Please note that some targeting attributes require stricter controls on the telemetry than can be collected, so when in doubt, ask for review.

## Detailed usage
### `addonsInfo`
Provides information about the add-ons the user has installed.
Note that the `name`, `userDisabled`, and `installDate` is only available if `isFullData` is `true` (this is usually not the case right at start-up).
**Due to an existing bug, `userDisabled` is not currently available**
#### Examples
* Has the user installed the unicorn addon?
```java
addonsInfo.addons["unicornaddon@mozilla.org"]
```
* Has the user installed and disabled the unicorn addon?
```java
addonsInfo.isFullData && addonsInfo.addons["unicornaddon@mozilla.org"].userDisabled
```
#### Definition
```ts
declare const addonsInfo: Promise<AddonsInfoResponse>;
interface AddonsInfoResponse {
// Does this include extra information requiring I/O?
isFullData: boolean;
// addonId should be something like activity-stream@mozilla.org
[addonId: string]: {
// Version of the add-on
version: string;
// (string) e.g. "extension"
type: AddonType;
// Version of the add-on
isSystem: boolean;
// Is the add-on a webextension?
isWebExtension: boolean;
// The name of the add-on
name: string;
// Is the add-on disabled?
// CURRENTLY UNAVAILABLE due to an outstanding bug
userDisabled: boolean;
// When was it installed? e.g. "2018-03-10T03:41:06.000Z"
installDate: string;
};
}
```
### `attributionData`
An object containing information on exactly how Firefox was downloaded
#### Examples
* Was the browser installed via the `"back_to_school"` campaign?
```java
attributionData && attributionData.campaign == "back_to_school"
```
#### Definition
```ts
declare const attributionData: AttributionCode;
interface AttributionCode {
// Descriptor for where the download started from
campaign: string,
// A source, like addons.mozilla.org, or google.com
source: string,
// The medium for the download, like if this was referral
medium: string,
// Additional content, like an addonID for instance
content: string
}
```
### `browserSettings`
* `update`, which has information about Firefox update channel
#### Examples
* Is updating enabled?
```java
browserSettings.update.enabled
```
* Is beta channel?
```js
browserSettings.update.channel == 'beta'
```
#### Definition
```ts
declare const browserSettings: {
attribution: undefined | {
// Referring partner domain, when install happens via a known partner
// e.g. google.com
source: string;
// category of the source, such as "organic" for a search engine
// e.g. organic
medium: string;
// identifier of the particular campaign that led to the download of the product
// e.g. back_to_school
campaign: string;
// identifier to indicate the particular link within a campaign
// e.g. https://mozilla.org/some-page
content: string;
},
update: {
// Is auto-downloading enabled?
autoDownload: boolean;
// What release channel, e.g. "nightly"
channel: string;
// Is updating enabled?
enabled: boolean;
}
}
```
### `currentDate`
The current date at the moment message targeting is checked.
#### Examples
* Is the current date after Oct 3, 2018?
```java
currentDate > "Wed Oct 03 2018 00:00:00"|date
```
#### Definition
```ts
declare const currentDate; ECMA262DateString;
// ECMA262DateString = Date.toString()
type ECMA262DateString = string;
```
### `devToolsOpenedCount`
Number of usages of the web console.
#### Examples
* Has the user opened the web console more than 10 times?
```java
devToolsOpenedCount > 10
```
#### Definition
```ts
declare const devToolsOpenedCount: number;
```
### `isDefaultBrowser`
Is Firefox the user's default browser?
#### Definition
```ts
declare const isDefaultBrowser: boolean;
```
### `isDefaultHandler`
Is Firefox the user's default handler for various file extensions?
Windows-only.
#### Definition
```ts
declare const isDefaultHandler: {
pdf: boolean;
html: boolean;
};
```
#### Examples
* Is Firefox the default PDF handler?
```ts
isDefaultHandler.pdf
```
### `defaultPDFHandler`
Information about the user's default PDF handler

### `messageImpressions`
Dictionary that maps message ids to impression timestamps. Timestamps are stored in
consecutive order. Can be used to detect first impression of a message, number of
impressions. Can be used in targeting to show a message if another message has been
seen.
Impressions are used for frequency capping so we only store them if the message has
`frequency` configured.
Impressions for badges might not work as expected: we add a badge for every opened
window so the number of impressions stored might be higher than expected. Additionally
not all badges have `frequency` cap so `messageImpressions` might not be defined.
Badge impressions should not be used for targeting.
