Frequently Asked Questions

  • 1. What is Network Information?

    Network Information is a lite and multi-browser add-on that provides information about your systems connection. It is working based on a new Javascript API called "navigator.connection". Currently, all modern browsers support this API, but the amount of information provided may vary depending on the browser and platform. For example, Chrome provides the most available information about your system connection and Firefox provides the least amount (Firefox on desktop machines). When you open the toolbar popup UI, there is a big speed gauge plot at the top center which shows the downlink speed for your browser. This speed refers to the estimated bandwidth in megabits per second; and is not related to the current internet speed at all. Other metrics for the network information API are discussed below. There is a reload button at the top right corner of the screen which is for reloading the app UI. There is also a wifi icon at the middle right section of the screen which shows the online or offline status of your browser.

  • 2. How can I work with Network Information add-on?

    Woking with this add-on is very easy. Simply open the toolbar popup UI and see the available info about your device connection. From the top to bottom there is a speed gauge that shows the estimated bandwidth for your system in megabits per second. Below the gauge is a bullet list for the remaining metrics in the API. The first item is connection type which can be Bluetooth, cellular, ethernet, wifi or other. The next item is the connection RTT in milliseconds. RTT refers to the round trip time for your network, meaning the time spent to send a signal to a server and receive the response back. It is a very useful metric for web developers and site SEO to measure page speed. Next item is the saveData attribute which, if true, indicates that your browser is using a reduced data usage mechanism. The fourth item refers to the maximum downlink speed explained above. Number 5 is the - effectiveType - attribute which refers to the effective type of the connection (2g, 3g, 4g, etc.). The last item is the downlink value discussed above. There is also a wifi icon at the right middle section in the UI which shows the online/offline status of your browser. Please note that reloading the UI via the reload button at the top right corner, updates network information metrics.

  • 3. How can I download the source code for Network Information?

    To download the source code for this extension from Chrome Web Store, it is recommended to use Extension Source Downloader. With this addon, you can download the source code as a ZIP or CRX format to your machine. If you want to download the source code from the Firefox addons store, please open the firefox download link (if available) in the Firefox browser and then right-click on the - Add to Firefox - button and select - Save Link As... - item. Choose the destination folder on your machine and then save the file in XPI format. You can then rename the XPI format to a RAR or ZIP file. Some extensions may have a GitHub repo address, which you can use to download the source code as well. But, it may not be the latest version of the addon. Therefore, downloading the source code from the official web stores is the best option as it always gives you the latest version of the addon.

  • 4. How does the network information add-on work?

    This add-on works based on the HTML5 - navigator.connection - API. All modern browsers support this new JavaScript API. Moreover, it works for both mobile and desktop machines on all operating systems. Currently, the Firefox browser in desktop machines has very limited support for this API. Therefore this add-on is not currently released for Firefox browser.

  • 5. Is there any options or setting page available for this addon?

    No, this add-on has no settings or options to adjust. Everything you need is placed in the toolbar popup UI.

  • 6. Can I open network information UI inside the active tab content, instead of toolbar popup UI?

    No, the UI is only available in toolbar popup. Currently, it is not designed to be opened inside the HTML page.

  • 7. How can I refresh the network information values rendered in the popup UI?

    If you want to refresh the information in the popup, please reload the UI via the reload button at the top right corner of the screen. Alternatively, you can close and open the popup to see the updated info.

  • 8. When the popup UI is closed, is there any background activities related to this add-on?

    No, when the toolbar popup is closed, the addon has no background activities at all.

  • 9. Do all browsers support all the six metrics for the network information API?

    No, unfortunately currently this API has limited support in modern browsers and each browser shows a certain number of metrics depending on its version or operating system. As mentioned above, the Firefox browser, desktop version, has very limited support for this API. Therefore, this add-on is not currently released for the Firefox browser.
