Firefox runs slowly on Windows 7 when there are numerous tabs open.
You're noticing a common issue with modern browsers and web apps. The performance drop with many open tabs often stems from how browsers handle JavaScript-heavy pages. It's not necessarily a flaw in your hardware—your Core i5, 8GB RAM, and SSD should handle it well—but the software might be inefficient. Check if extensions or background scripts are slowing things down, and consider optimizing tabs or using lighter browsers.
