Cleanup Gmail bởi Ascenso Labs

Drowning in unread emails and annoying Gmail push notifications? Take back your inbox! After a quick one-time setup, this add-on gives you a simple, one-click solution to instantly bulk-mark thousands of emails as read with zero guesswork.

The Problem
Marking thousands of emails as read in the default Gmail interface is surprisingly complicated. You have to navigate hidden menus to select all conversations, and when you finally click the button, there is almost no visual feedback. You are left staring at the screen, wondering if the action actually worked or if it is just stuck loading in the background.

The Smart Solution
CleanupGmail takes the confusion out of the process. Instead of wrestling with Gmail's interface, you click a single button in the extension. It offloads the heavy lifting directly to Google's own cloud network, giving you a real-time progress bar as feedback so you know exactly how many emails are being processed at any given moment.

Privacy First, Zero Telemetry
Your inbox is highly personal, and you shouldn't have to hand over access to a third-party server just to clean it up. Because this extension is built on a strict privacy-first architecture, there are:
* No intermediary servers
* No analytics
* Absolutely zero telemetry
This add-on is fully open-source (GPLv3) and available on GitHub, completely transparent, and 100% controlled by you.

Key Features
* One-Click Bulk Clear: Instantly wipe out 99,999+ unread counts and silence those push notifications for good, whenever you want.
* Real-Time Feedback: Watch the progress bar update live as the cloud processes your emails. No more wondering if it actually worked!
* Multi-Account Support: Seamlessly switch between Personal, Work, or side-hustle Gmail profiles.
* Cross-Device Sync: Native Firefox Sync securely backs up your profiles so they are ready on all your devices.

Minimal, One-Time Setup
Because we refuse to use third-party servers to process your private data, this add-on requires a brief, 2-minute initial setup.

The extension provides a short, readable, open-source script that you simply copy and paste into your own Google Apps Script dashboard. This acts as your own private, highly secure backend engine. You only have to do this once per email account, and you retain the power to review the code and revoke its access at any time!
