Glassdoor Paywall Remover Update

Technical summary

This project is a highly optimized userscript written in vanilla JavaScript designed to bypass Glassdoor's intrusive paywall mechanisms and forced authentication modals. Glassdoor restricts access for unauthenticated guest users by dynamically rendering a full-screen signup modal, applying an overflow: hidden style modifier to the body element, and fully blocking the scrolling functionality to restrict access to company reviews, salary details, and job listings.

Executed scope

• High-Priority CSS Override: Developed early-stage stylesheet injection routines running at @run-at document-start that force layout rules using !important flags to override body scroll locking and obscure dynamic modal overlay containers.
• Resilient MutationObserver: Implemented a robust DOM MutationObserver configured to monitor subtree additions in the document root. The script identifies key DOM signatures of the forced authentication modal and purges them asynchronously without consuming unnecessary CPU cycles.
• Anti-Adblock Mitigation: Handled specific platform triggers that detect the deletion of the signup modal and attempt to hide the inner job review content.

Stack and tooling

• Vanilla JavaScript (ES6+): Lightweight, framework-free implementation ensuring zero runtime overhead.
• Tampermonkey / Violentmonkey: User script managers chosen for clean local execution policy enforcement.
• MutationObserver API: Native browser API leveraged to observe and intercept asynchronous layout shifts in real time.
• CSS Style Injection: Direct runtime injection of overriding rules to restore natural scrolling behaviors on the body element.

Operational tags

• Userscript
• Glassdoor
• JavaScript

Operational outcome

• Delivery oriented to real execution in desktop and mobile browsers, focused on predictability and maintainability.
• Structure prepared for incremental evolution via repository versioning on GitHub.
