It has lots of great features including popup-blocking, tabbed-browsing, integrated search, improved privacy features, automatic updating and more. The story of Firefox and Firebug are synonymous with the rise of the web. We fought the good fight and changed how developers inspect HTML and debug JS in the browser. Firebug ushered the Web 2.0 era. Today, the work pioneered by the Firebug community through the last 12 years lives on in Firefox Developer Tools.
Firefox (latest version, 43.0.4) is causing my HDD to run between 98% and 100% all the time and making heavy CPU demands too, fluctuating between 30% and 70% CPU being used by Firefox. I've tried clearing my cache and cookies etc. And I've tried starting Firefox in Safe Mode. Again no change. Firefox supports Web Audio API, along with more than 30 other Web APIs, many of which were prompted by Mozilla's ill-fated Firefox OS mobile platform initiative. Many, such as mouse-lock.

Installation
Installing Firefox was a fine , quick experience.A new feature checks your add-ons to see which ones you installed and which ones come from third-party vendors, such as security suite makers. The browser will now ask you if you'd like to disable any of these third-party add-ons.
Interface
The menu bar has been squished into an orange button on the upper left, with menu options spread across two columns.the menu makes it much easier to get to bookmarks, add-ons, and history, as they now all live on one Menu pane.
Performance
Firefox is built on top of the powerful new Gecko platform, resulting in a safer, easier to use and more personal product.Mozilla plans to crowdsource its performance data to learn more about how the browser performs in real-world situations.
Features
Firefox's features are robust and generally competitive. The most important feature in the modern Firefox is Sync.Sync now smoothly syncs your bookmarks, passwords, preferences, history, and tabs, not only with other computers, but also with your Android version of Firefox.
