FAQ

  1. Where can I see the change-log of this extension?

    I usually add a summary of change-logs in here. For more through log check the GitHub commit section.

  2. What is about:performance?

    Performance Monitor is a new internal page in the Firefox browser that displays slow add-on alerts and resource usage of the browser starting with Firefox 40. The performance monitor divides data into performance related information that update automatically while you are using the browser and slow add-ons alerts which seems to use the new slow add-on notification system that Mozilla integrated in Firefox 38 Nightly.

  3. Why Performance Reporter is only available for Firefox Nightly?

    Performance Reporter is a wrapper to the about:performance built-in tool introduced in Firefox 40.0. Although the UI has slightly been modified to be better presented within a toolbar panel.

  4. Where can I find more info about all the perfomance related tools available in Firefox browser?

    Check https://developer.mozilla.org/en-US/docs/Tools/Performance for more info. Note that this is a technical document.

  5. Is Performance Reporter still monitors tabs and extensions while the panel is not shown?

    No! due to performance enhancement, the UI is completely unloaded when the panel is closed. In fact, the UI is replaced with about:blank to use as minimum memory as possible.

  6. How can I request a new feature for this extension?

    Please read the Help section. The easiest and fastest way to reach me is to open a bug in the GitHub rp.

  7. What are the elements in the reporter panel (more technical)?

    The table layout of the Performance Monitor in Firefox is intended to show you the load of the JavaScript engine. Using those values, it is possible to tell which tab, which site and which scripts affect the browser's performance and cause a heavy load on Firefox's processes. While there is no official information about this feature, it can be quite useful for all Firefox users even in the current state. The Performance Monitor feature is part of the JavaScript subsystem of the Firefox browser and it adds per-compartment CPU accounting.

Editorial Review

Surfing over the INTERNET has never been easy. For people who need tons of information, scrolling through different pages, keeping the domain name in mind and then putting together that information is a daunting task. If we ever see a multitasking individual, we will see probably more than twenty tabs opened, which is not only confusing but a nuisance as well. For this reason, we were introduced to a number of different add-ons. These add-ons started off from helping us in our search at first, but with time, they were attached to social media platforms as well, to help us in any way possible. From Facebook to YouTube, these add-ons have made life easier for us in every step of the journey. Add-ons have been made to provide us with easy access throughout the INTERNET, and to find any data we are looking for, faster. This not only saves time but also the effort you put in searching for different things. However, no matter how user-friendly and helpful these add-ons are, they still consume CPU usage and storage, which needs to be calculated from time to time. This is where Performance Reporter comes into play.

Performance Reporter is a convenient add-on, which helps in calculating the CPU usage and storage consumption of these add-ons. This extension is extremely lightweight, and it helps in showing all the memory usage of tabs and add-on, you have installed over your device. Moreover, the high CPU usage of any add-on is color coded, in order to demonstrate which add-on is taking up to much space on your device. This helps is keeping a track of all heavyweight add-ons in the device. Above all, the Performance Reporter version 0.1.1 is easy-to-use for everyone.

I would recommend this add-on to everyone, especially people who want to keep a check on the CPU and memory usage of all their tabs and add-ons.
