How do browsers like Chrome, Edge, and Opera outperform Firefox in speed despite having more features and bloat?

@babitakumari and @dimplesaini.230 told about the pros of the pro browsers, but let’s understand why not Firefox? Or if there is some good in it, what is it?

While Firefox is often slower than Chrome and Edge in raw speed, it excels in privacy and customization. Mozilla’s Firefox is built with a strong emphasis on privacy features like Enhanced Tracking Protection, which can sometimes reduce its speed compared to Chromium-based browsers.

Firefox also offers more customizability in terms of add-ons and user settings, which can sometimes lead to more overhead. However, the performance differences are typically more noticeable on resource-heavy sites and when you have many tabs open. For users who prioritize privacy over speed, Firefox remains a solid choice.

If you’re testing Firefox’s performance or comparing its speed to Chrome or Edge, tools like LambdaTest are invaluable for cross-browser testing. You can simulate performance on Firefox across various devices and screen sizes, allowing you to pinpoint slow-loading elements on your site or app and optimize accordingly.

Speedometer 2.0 Score: Is 164 ± 13 Good?

A score of 164 ± 13 on Speedometer 2.0 is decent but not extraordinary. Speedometer tests a browser’s responsiveness by simulating real-world web applications, so a higher score generally indicates better performance.

For comparison, modern browsers like Chrome and Edge often score higher, but a 164 score is still acceptable for most everyday browsing needs. If you’re developing a web application, it’s a good idea to use LambdaTest to test your site across different browsers and devices to optimize it for performance, especially if you want to improve your Speedometer score in future tests.

Thanks! :grin:
