Snoozer is a Chrome extension that lets you snooze conversations on messenger.com.
Snoozing a conversation hides it from view for a specified amount of time. After that time expires, the conversation will automatically reappear with an orange visual indicator. To snooze a conversation, hover over it in the left sidebar and click the clock button.
There are many different use cases for snoozing messages. The most common use case is to snooze messages that require a response from you, but you can't or don't want to respond immediately. Snoozing these messages reduces the visual clutter and mental burden of keeping track of your actionable conversations.
You can always view all of your snoozed conversations at any time by clicking the large clock button in the upper-left corner of the page. You can also manually desnooze conversations if desired.
Note: Snoozer is only compatible with messenger.com and will not affect your experience on facebook.com or mobile applications.
