Issue: Critical Rendering Failure and Script Latency on Polybuzz.ai I am reporting a consistent issue where modern AI platforms, specifically Polybuzz.ai, fail to function correctly on Firefox (both Android and Linux). Despite being a loyal user since 2004, the current performance gap compared to Chromium browsers is making daily tasks impossible. Core Technical Problems: Layout Corruption: Even in Desktop Mode, the UI breaks, elements overlap, and CSS grids do not render properly. High Input Lag: Massive delays in JavaScript execution, causing the browser to become unresponsive during site interaction. Engine-Level Issues: The problem persists on both Android (latest stable) and Linux (Zorin OS/Linux Mint), suggesting a fundamental issue with the Gecko engine's handling of heavy AI frameworks. Troubleshooting Done: Tested with Enhanced Tracking Protection both ON (Standard) and OFF. Cleared all site data and cache. Verified that the same site runs smoothly on Chromium-based browsers on the same network/device. Please investigate Gecko’s compatibility with these modern web standards. Screenshots of the broken UI are attached for reference.
