Besides above settings, notification will wait 5 minutes before showing the first notification on a new profile or the updated user profile (to not put too much information to the user at once).
To manually remove the mute duration, set pref `browser.onboarding.notification.mute-duration-on-first-session-ms` to `0` and notification will be shown at the next time you open `about:home` or `about:newtab`.
## How to show the snippets
Snippets (the remote notification that handled by activity stream) will only be shown after onboarding notifications are all done. You can set preference `browser.onboarding.notification.finished` to `true` to disable onboarding notification and accept snippets right away.
`OnboardingTourType.jsm` will check the onboarding tour type (currently support `new` and `update`). Then in `onboarding.js`, All tours are defined inside of `onboardingTourset` dictionary. `getTourIDList` function will load tours from proper preferences. (Check `How to change the order of tours` section for more detail).
When user clicks the action button in each tour, We use [UITour](http://bedrock.readthedocs.io/en/latest/uitour.html) to highlight the correspondent browser UI element. The UITour client is bundled in onboarding addon via `jar.mn`.
Edit `browser/app/profile/firefox.js` and modify `browser.onboarding.newtour` for the new user tour or `browser.onboarding.updatetour` for the update user tour. You can change the tour list and the order by concate `tourIds` with `,` sign. You can find available `tourId` from `onboardingTourset` in `onboarding.js`.
## How to pump tour set version after update tours
The tourset version is used to track the last major tourset change version. The `tourset-version` pref store the major tourset version (ex: `1`) but not the current browser version. When browser update to the next version (ex: 58, 59) the tourset pref is still `1` if we didn't do any major tourset update.
Once the tour set version is updated (ex: `2`), onboarding overlay should show the update tour to the updated user (ex: update from v56 -> v57), even when user has watched the previous tours or preferred to hide the previous tours.
