Intercom Counter от Vladimir Gusev

Intercom Counter is a lightweight Firefox extension for tracking daily support activity in Intercom.

It shows three local daily counters:

• Dialogs: conversations where you sent your first reply today
• Replies: every reply you send today
• Closed: conversations you close today

The extension works only on https://app.intercom.com/ and stores counters locally in Firefox storage. It does not send analytics, telemetry, account data, message contents, or browsing data to any external server.
