AI product read

Blocks and hides ads on webmail services (Gmail, Outlook.com, Yahoo Mail) by injecting CSS rules that hide ad elements and adjust page layout to give more screen space to email content.

Webmail services display ads in the sidebar, above/below inbox, and inline with messages that clutter the interface and reduce usable space for reading emails. This extension removes those ads for a cleaner, more focused email experience.

User installs the extension. The content script (webmailAdBlocker.js) automatically runs on Gmail, Outlook, and Yahoo Mail pages, injecting CSS to hide ad elements. The user can click the extension icon to see status and toggle blocking on/off for the current site. The options page allows enabling/disabling host permissions per webmail service. No login or configuration is required for basic use.

Target users: Gmail users / Outlook.com/Hotmail users / Yahoo Mail users / Parents seeking to child-proof webmail ads / Users wanting a cleaner email interface

The common.js and jdom.js files are large shared libraries reused across the developer's (Jason Savard) multiple extensions; paid/login infrastructure (Stripe CSP, getPaypalLC, mustDonate, chrome-sign-in-button) is inherited shared code not specific to this extension's functionality.
Cannot fully verify if the contribute/donation dialog actually gates any options in this specific extension since the options.html uses only standard checkbox toggles for host permissions.
