Firefox Browser Online

While Microsoft's Internet Explorer still comes pre-installed on most Windows-based PCs, clearly Microsoft would prefer you to use their Edge browser, which is set as the default when you purchase.

Mozilla Firefox is a feature-rich and highly customizable web browser that's user-friendly enough for beginners and sophisticated enough for advanced users. Firefox has managed to retain significant market share despite stiff competition from Google Chrome and Microsoft Internet Explorer and Edge.

Microsoft discontinued its Internet Explorer brand several years ago, in favor of its updated Edge browser for Windows 10. However, slow adoption for Edge created room for Internet Explorer to live on, mainly for business compatibility reasons.

Here we'll compare our Firefox Browser with Internet Explorer in terms of security, utility, and portability. We'll help you understand the differences between how a modern browser like Firefox that adheres to web standards compares with the browser you may be using for business purposes or out of old habits that die hard.

If you haven't moved on from using Internet Explorer, the security risk factor alone should be enough to convince you. Microsoft's own security chief has warned millions of people who continue to use Internet Explorer as their main web browser that they are placing themselves in 'peril.'

Microsoft is no longer supporting new development for Internet Explorer, which means security concerns are rampant. Microsoft openly acknowledges the fact that vulnerabilities exist within basically every version of Internet Explorer.

So what's the solution if your company is running legacy apps that only work on Internet Explorer? Our best advice is, don't mix business with pleasure. We actually recommend use of the Legacy Browser Support extension for Windows. This extension lets users automatically open a predefined set of URLs in Internet Explorer and switch back to Firefox when navigating to a different domain.

Utility

Firefox Web Browser Online

Alarmingly, 4 to 5% of all desktop web traffic came through Internet Explorer as recently as 2019. That might not seem like a lot, but in reality it means millions of people are being served a poor internet experience with slow loading and rendering times, pages that won't display properly — all on top of the security issues already discussed.

Really the only reasons to use Internet Explorer are for developers to test what their sites look like on an older browser or if a company has business-critical apps that only work with the Internet Explorer browser.

On the other end of the spectrum, Firefox is one of the most frequently updated browsers, and comes loaded with lots of useful and interesting features, like Pocket that suggests interesting content every time you open a new tab. Our unified search and web address bar, or Quantum Bar as we call it, also gives you suggestions based on your existing bookmarks and tags, history, open tabs and popular searches. And with a free Firefox account you also get access to all your settings and our other Firefox products on any device simply by signing in. Plus the peace of mind of knowing your browser is proactively working to protect your personal data.

As Microsoft has made the move to sunset the Internet Explorer browser, it no longer supports any version for iOS, and has never been available for Android. Which means unless you're running a Windows-based laptop or desktop, you won't have access to your bookmarks, browsing history, saved passwords, and other information that modern browsers sync across devices.

Firefox works on any platform, including Windows, macOS, Linux, Android and iOS. Which also means you can sync all your information across platforms. So if you're browsing on a Windows-based laptop, you can pick up where you left off when you move to browsing on your iPhone or Android device. This convenience should come standard with any modern web browser, and is sorely lacking with Internet Explorer.

Overall Assessment

There was a time not so long ago where Internet Explorer was the most popular and widely used browser in the world. Times have changed and so has technology, but unfortunately Internet Explorer has pretty much stayed the same. Microsoft itself openly implores users to stop using Internet Explorer and instead switch to their newer Chromium-based Edge browser.

Our opinion is just to go with a trusted, private browser with a track record of delivering a great experience across devices. In a head-to-head comparison, it's really no contest at all. Firefox is hands down the winner across all assessment categories. If you do find yourself at Nana's house firing up Internet Explorer, maybe you want to do Nana a favor and download Firefox for her.

The comparisons made here were done so with default settings and across browser release versions as follows:

Some browsers implement Online/Offline events from the WHATWG Web Applications 1.0 specification.

Overview

In order to build a good offline-capable web application, you need to know when your application is actually offline. You also need to know when your application has returned to an 'online' status again. Effectively, the requirements break down as such:

1. You need to know when the user comes back online, so that you can re-synchronize with the server.
2. You need to know when the user is offline, so that you can queue your server requests for a later time.

It is this process that online/offline events help to simplify.

Unfortunately, these events aren't fully reliable. If you need greater reliability, or if the API isn't implemented in the browser, you can use other signals to detect if you are offline including using service workers and responses from XMLHttpRequest.

API

navigator.onLine

navigator.onLine is a property that maintains a true/false value (true for online, false for offline).

This property is updated whenever the user switches into 'Offline Mode' (File → Work Offline in Firefox). Additionally, this property should update whenever a browser is no longer capable of connecting to the network. According to the specification:

The navigator.onLine attribute must return false if the user agent will not contact the network when the user follows links or when a script requests a remote page (or knows that such an attempt would fail)...

Firefox 2 updates this property when switching to/from the browser's Offline mode. Firefox 41 updates this property also when the OS reports a change in network connectivity on Windows, Linux, and OS X.

This property existed in older versions of Firefox and Internet Explorer (the specification based itself off of these prior implementations), so you can begin using it immediately. Network status autodetection was implemented in Firefox 2.

'online' and 'offline' events

Firefox 3 introduces two new events: 'online' and 'offline'. These two events are fired on the of each page when the browser switches between online and offline mode. Additionally, the events bubble up from document.body, to document, ending at window. Both events are non-cancellable (you can't prevent the user from coming online, or going offline).

Firefox 41 fires these events when the OS reports a change in network connectivity on Windows, Linux, and OS X.

You can register listeners for these events in a few familiar ways:

• using addEventListener on the window, document, or document.body
• by setting the .ononline or .onoffline properties on document or document.body to a JavaScript Function object. (Note: using window.ononline or window.onoffline will not work for compatibility reasons.)
• by specifying ononline='...' or onoffline='...' attributes on the tag in the HTML markup.

Example

Firefox Browser Online

There's a simple test case that you can run to verify that the events are working (does not work in Chrome due to attaching the event listener to document.body).

Here's the JavaScript part:

A touch of CSS

And the corresponding HTMLXXX When mochitests for this are created, point to those instead and update this example -nickolay

Here's the live result

Notes

If the API isn't implemented in the browser, you can use other signals to detect if you are offline including using service workers and responses from XMLHttpRequest.
