Suggested March 2024 Firefox Json Viewer Not Working; Cannot View Or Edit Json Data

JSON is viewable in Mozilla Firefox, but there might come a time when you find it difficult to view this piece of information. Not only that, but it is possible to edit JSON data in Firefox as well, so if you are having problems with viewing or editing, worry not, for there are ways to solve this. JSON is an open-standard file format that uses human-readable text to transmit and store data.

Firefox JSON Viewer not working

Now, most folks who want to view and edit JSON data are likely to be programmers rather than regular folks. And that is why reading and editing such data is essential where Firefox is concerned because it is the browser of choice for many programmers. You have three options:

Is the JSON Viewer disabled? Enable it

Use a Firefox JSON Extension

Use an online JSON Editor tool.

Enable JSON Viewer in Firefox

If you cannot view JSON information in Firefox, then chances are the feature is disabled. The best option in a situation such as this one is to re-enable it. We can do this by copying and pasting the following in the URL bar:


After that is done, hit the Enter key to open the about:config page that is filled with a ton of options to play with.

The next step, then, is to copy and paste the following in the search box:


If the value is set to False, then it means the feature is disabled.

Restart your web browser, then attempt to read JSON files once more.

Use a Firefox JSON extension

If this does not work for you, you may use one of the following extensions:

1] JSON Lite Extension

If you’re not keen on using the built-in JSON viewer, we would like to recommend JSON Lite. It’s an extension for Firefox, and from our testing, it appears to work quite well.

Bear in mind that before using JSON Lite, you must first disable the built-in option via the about:config area.

Download the extension from the official website.

2] JSONView Extension

Another extension that works very well for viewing JSON files is one called JSONView. The cool thing about this extension is the fact that it doesn’t require users to disable the built-in viewer, so no extra work on your part.

Download the extension via the official website.

Use an online JSON Editor tool 1] JSON Editor Online

Viewing is just one aspect of using JSON files. The other is the ability to edit, and JSON Editor Online is one of the best tools out there to get the job done in the Firefox web browser.

We like this tool because it has a section for your code and another for the tree. With simple presses of the mouse, you can copy your code into the tree section with ease.

It’s a capable tool so give it a test drive to see if you find it pleasing for regular use.

2] Edit JSON Online

What we have here is another online tool for editing your JSON data.

It may not as powerful as the previous tool but still capable enough for users to get work done.

TIP: Here are some other useful online JSON Tools that may help you.

Learn Working Of Json In Swift With Examples

Introduction to Swift JSON

Swift JSON is used for communication of the IOS web application with the server by returning a series of formatted data or information. This formatted data organized in a proper hierarchical manner is called Swift JSON. Foundation framework that includes a class called JSONSerialization is exclusively used for converting any JSON involved within the web application into Swift data types like array, number, bool, String, and Dictionary. It is very difficult to predict the actual structure or the order in which values of JSON-based web applications will receive as part of returned data.

Web development, programming languages, Software testing & others

There is no proper syntax for any Swift JSON it can be any resource file containing the data in an ordered manner as represented below but then indentation does matter while validating any JSON data as improper JSON input might vary and can behave differently while parsing and traversing as well.

{ "title": "some_data", "url": "any_url_can_be_included", "category": "Category_for_swift_language", "views": 25648 } How JSON works in Swift?

JSON parsing or manipulation with JSON in any programming language is a common functionality when any web application tries to communicate with the other server.

Any web application dealing with JSON data tries to decode the JSON data in an ordered manner. Swift JSON parsing is very important for any IOS developer as they will most often get acquainted with these kinds of data.

Decoding modules in swift are quite flexible and are very easy to understand without any indulgence of external API.

There are times when swift JSON containing JSONSerialization class method returns a value of any type and throws error in case the data cannot get parsed easily then a proper validation with error elicitation will be given to the user for identification of the actual exception.

Although the JSON data will get validated still there will be times when JSON may contain a single value, a response from a web application can encode an object or array as any top-level object for manipulation.

All the data types related to swift get used as per requirement and any optional value can be considered for it.

There is quite a need to create Model objects from the Model-view-controller design pattern that are often used to convert json data to objects which are specific to the application’s domain in a model view.

If the applications are related to one or more web services do not return a single, or consistent model for the representation of a model object, considering implementation of several initializers to handle all the possible representations.

JSON initializer helps a lot when it comes to extracting and getting the detailed implementation with errors and exceptions. Error Handling with error protocols helps in deserialization with the fail for protocol.

Many times, it happens that the application returns multiple endpoints for any resource that returns a single JSON response following any particular protocol.

A search endpoint may return zero or more endpoints then in that case the requested query may contain more or other metadata while presenting for the endpoint.

JSON parser plays a pivotal role in parsing as it helps in making the entire JSON data organized in a properly visualized format which gives an impression that the data can be organized in a proper manner.

Swift is the programming language that allows programmers to use and make the data ordered and visualized in a very easy and effective manner by giving an idea of proper idealization and organization for operations and manipulations.

Examples of Swift JSON

Here are the following examples mentioned below.

Example #1

This program demonstrates the JSON data where the input feed is represented as follows and the output feed after execution of the JSON parsing comes out to be shown as output. But it makes the Sample usage feed with the codeable mapping.


{ "title": "Usage of the optional Swift language.", "version": "4.0", "category": "Swift_version", "views": 25642 }


Example #2

This program demonstrates the JSON data where the input feed is represented with the same input as example 1 but with the mere difference of the fact that the JSON decoder will make use of the Object mapper for conversion of JSON String to model. This is shown in the output as shown:


{ "title": "Usage of the optional Swift language.", "version": "4.0", "category": "Swift_version", "views": 25642 }


Example #3

This program demonstrates the JSON data where the input feed is represented with the same input as example 1 but with the more difference of the fact that the JSON decoder will make use of the dictionary mapper for conversion of JSON String to model. This is shown in the output as shown:

{ "title": "Usage of the optional Swift language.", "version": "4.0", "category": "Swift_version", "views": 25642 }


Example #4

This program demonstrates the custom mapping for each defined key with the mapping of a blog and key and value pairs with the JSON and making the key encoding as the main conversion of the JSON to a blog.


{ "title": "Sat_Sun_Week:end_Comboff", "version": "swift_version_4.0", "visitors_way": 258965, "posts_for_members": 62542 }


Example #5

This program demonstrates the custom mapping for each defined key with the mapping of a blog and key and value pairs with the JSON and making the Object mapper in use for representation as shown in the output.

{ "title": "Sat_Sun_Week:end_Comboff", "version": "swift_version_4.0", "visitors_way": 258965, "posts_for_members": 62542 }


Example #6

This program demonstrates the custom mapping for each defined key with the mapping of a blog, key and value pairs with the JSON and making the Dictionary mapper in use for representation as shown in the output.


{ "title": "Sat_Sun_Week:end_Comboff", "version": "swift_version_4.0", "visitors_way": 258965, "posts_for_members": 62542 }



Swift JSON is the proper way of validating and making the entire data set and information organized in a visualized manner for the programmers. The successful communication between any web application and server helps a lot to analyze the entire application for product analysis and division of information uniformly among all applications efficiently.

How To Serialize A Polyline Object Into Json In Fabricjs?

A polyline object can be characterised by a set of connected straight-line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity, etc.

Serialization means converting the canvas into savable data which can be converted back into the canvas later. This data can be an object or JSON so that it can be stored on servers. We will use the toJSON() method to convert the canvas with Polyline object into JSON.

Syntax toJSON(propertiesToInclude: Array): Object Parameters

propertiesToInclude − This parameter accepts an Array which contains any properties we might want to additionally include in the output. This parameter is optional.

Example 1: Using the toJSON Method

Let’s see a code example to see the logged output when the toJSON method is used. In this case, a JSON representation of the Polyline instance will be returned.

var canvas = new fabric.Canvas(“canvas”); canvas.setWidth(document.body.scrollWidth); canvas.setHeight(250);

var polyLine = new fabric.Polyline([ { x: 500, y: 20 }, { x: 550, y: 60 }, { x: 550, y: 200 }, { x: 350, y: 100 }, { x: 350, y: 60 }, ], { stroke: “orange”, fill: “white”, strokeWidth: 5, });


console.log(“JSON representation of the Polyline instance is: “, polyLine.toJSON());

Example 2: Using toJSON Method to Add Additional Properties

Let’s see a code example to see how we can include additional properties by using the toJSON method. In this case, we have added a custom property called “name”. We can pass the specific property to the fabric.Polyline instance as second argument in options object and pass the same key to the toJSON method.

var canvas = new fabric.Canvas(“canvas”); canvas.setWidth(document.body.scrollWidth); canvas.setHeight(250);

var polyLine = new fabric.Polyline([ { x: 500, y: 20 }, { x: 550, y: 60 }, { x: 550, y: 200 }, { x: 350, y: 100 }, { x: 350, y: 60 }, ], { stroke: “orange”, fill: “white”, strokeWidth: 5, name: “Polyline instance”, });


console.log( “JSON representation of the Polyline instance is: “, polyLine.toJSON([“name”]) );

Fix Chrome Crashing Or Not Working Issues

Chrome is the leading and most popular web browser in 2023, beating Apple Safari, Internet Explorer/Edge, and Firefox, which rank second, third and fourth respectively. Despite being number one, it has its downsides and its malfunctions, too. Many of its users have reported Chrome crashing, freezing, not responding or just not working.

As frustrating as it can be, the good news is there are several fixes to resolving the problem. Before you switch to a different browser, here are some tried and tested solutions you can use to get Chrome back to a stable state.

Preliminary checks

Check the address bar for any typos in the URL

If the page takes too long to load, either your connection is slow or the page is busy.

If you’re using a VPN, a particular website may hinder the browser from connecting

If you’re getting the “Aw Snap!” message, a plugin could be causing Chrome to crash

Refresh the page if any connection was interrupted while loading

Try using an incognito window. If the site works while in incognito, clear your browsing data

Restart Chrome

This is one of the most basic things to do before you try to troubleshoot why Chrome is crashing. It just involves closing Chrome completely and then reopening it, then trying to reload the page again to see if the problem disappears. You can also reopen the tabs you hadn’t closed and see if they all load again.

Try a different browser Restart your computer

A restart helps fix any software glitches that would cause the Google Chrome browser not to work or to crash. Sometimes apps and programs can stop pages from loading properly, so try to restart your computer and load the page or pages you had open on your browser again.

Close extensions, tabs and apps to free up memory

If your computer is low on memory, it may not be able to load sites and still run your apps, programs and extensions on your browser.

Remove or disable whatever you don’t use and delete any that shouldn’t be there.

Run a virus or malware scan

Viruses or malware on your computer could cause several problems, including Chrome crashing or not working. You can run a malware or virus scan using your system’s security software to spot and remove any resident threats that would be affecting Chrome’s normal operations.

Check for any software conflicts

Sometimes Chrome can conflict with other software or with Chrome itself and cause it not to work or crash altogether. This can be anything from network-related software to malware and any others that interfere with the browser.

To know which software conflicts with Chrome, go to chrome://conflicts on your browser’s address bar, and press Enter. Alternatively, you can go to Google and check for the software that caused Chrome to crash or not work properly.

You’ll also find the steps you can use to resolve any conflicts Chrome has with conflicting software on your system, but at best, you probably want to update your software to the latest version and disable or uninstall the problematic software.

Check for Chrome update

Chrome may crash or refuse to work if the software isn’t updated to the newest version. A new version or update can help patch any software glitches that cause this problem.

Fix hardware acceleration issues

Hardware acceleration hands graphical tasks to a different component other than your computer’s CPU, usually the GPU, for Chrome to run better. However, it can sometimes cause Chrome to crash or stop working.

Disabling this feature helps resolve problems with how Chrome and your computer hardware work together. To disable it:

Toggle the “Use hardware acceleration when available” to Off if it’s On and then restart the browser.

Fix Network and website issues

Chrome can also crash or stop working due to network or website issues. If the website doesn’t load properly, you can let the website owner know that you’re experiencing issues with it.

On the other hand, if you found that the page didn’t load when you tried a different browser, the issue could be your Internet connection or network. In this case, restart your modem or router.

Fix problematic apps stopping Chrome from working properly

Note: if the option is available, it means there’s a problematic app. If not, there’s no problem app.

You can update the apps from the app store if there’s an available update or check the app developer’s site for more details. You can also remove each app from the list if you prefer.

Reset and reinstall Chrome Wrap-Up

Few things are as frustrating as not being able to use your browser or when it freezes or crashes while you are enjoying your surfing experience. We hope these solutions helped resolve whatever caused Chrome to crash on your computer.
