Best Browser Add-ons to Analyze Page Speed
It is important to measure page speed by debugging a slow website.
All Chrome browsers have built-in tools to help troubleshoot why a page is slow and not performing as well as it could.
The advantage of Chrome and Firefox-based browsers is that they can be extended with tools that make troubleshooting sites quick and easy.
Chrome and Firefox support browser add-ons.
Firefox calls them add-ons and in the Chrome ecosystem they are called extensions.
Browser extensions and add-ons extend the functionality of browsers in a personalized way according to the user’s needs.
Why Use a Page Speed Browser Extension
A browser-based debugger like Chrome Developer Tools is a collection of tools, like a toolbox.
If you only want one tool, you’re out of luck because the browser offers the whole collection at once.
This means that an editor must first learn to navigate all the different menus, tabs, and screens, many of which offer tools that aren’t necessarily the big picture you want.
And that’s why extensions are a valid alternative to using a browser’s built-in troubleshooting tools.
You can simply choose the exact tool you want and skip the learning curve so you get the measurements you really need when you need them.

The Page Load Time browser extension for Chrome and also for Firefox provides a very accurate page load metric because it uses the Navigation Timing API, which is described on the Mozilla developer page for Navigation Time API.
The browser extension has been installed over 100,000 times and has been rated 258 times.
Once installed, all you need to do is visit a page and watch the Page Load Time icon in the top right corner of the browser.
