Hide Upgrade Button for Gmail

About

Declutter your Gmail toolbar. This extension hides the "Upgrade" button in the top-right of the Gmail interface, so your toolbar stays clean, focused, and distraction-free.

It does one thing, and only that one thing: it hides that single button. Nothing else on the page is changed.

How it works
• A tiny content script runs only on mail.google.com.
• It hides one specific toolbar element (Gmail's Workspace "global persistent entry point") and re-applies automatically as Gmail re-renders its interface.
• Nothing else on the page is touched.

Privacy
• No data is collected, stored, or transmitted.
• No analytics, no tracking, no external network requests.
• The extension has access to mail.google.com only, and uses it solely to hide one toolbar button.

Open and minimal: the entire extension is a manifest, one small script, one CSS rule, and icons.
