What Is A Browser Extension And From Where Do They Come?

software development

Extensions (or add-ons) are software components that, once integrated with your browser, allow you to expand its functionality, adding new features to the browser or modifying existing ones. They are useful in practice to improve the browsing experience, giving you the possibility to perform activities not otherwise possible by default with the browser.

They are free and almost always developed by third parties (i.e. not by the browser), so they are called a third-party extension.

Who are those third parties? There are a number of programmers and developers who create such extensions for the purpose to advance the browser they are personally using, or for the purpose to offer the world an idea, a concept made into a useful little program.

The modern concept of software development

This often implies the inclusion of only basic functions in the main program, and additional functionality is realized with the help of add-ons. Browsers are typical representatives of such an ideology. Of course, you need to understand that the basic functionality of any program is not a constant thing.

Programs are constantly evolving, acquiring new opportunities and discarding unnecessary ones. What initially appeared as an addition with time can enter into the basic functionality of the program. Often the developers of add-ons are completely outsiders or organizations that are not related to the developers of the main program.

People who need to be aware of the weather forecast or know the exchange rates can install such extensions. Of course, you can go to the relevant sites on the Internet and look there, or you can just install the appropriate extension in the browser and always have the necessary information before your eyes on its panel.

The plug-in can add support for any data format to the browser, and they can be viewed directly in the browser, without downloading to a computer and opening it in a third-party program. These examples are just tiny examples of what can be done with extensions. The possibilities are limited mostly by the imagination of developers and demand.

Want to find out how to use browser extensions?

First, download the ColorPick Eyedropper extension for Google Chrome. Then go to another site about choosing the best chopsticks. The chopsticks article has a lot of images you can now analyze with that fancy new browser plugin of yours.

Now let’s try another type of browser extension. Download the uBlock Origin extension for Firefox. Then go to the following 3 example pages about Pull Up Bars:

If you check the browser extension, you can see what tracking codes and advertisements were blocked on those three pull up bar sites.

Finally, after checking the tracking codes that were blocked with that extension, go to this article “how much does a stop sign cost?“. You’ll notice the stop sign article has less tracking codes than the eCommerce pages. But in all cases the browser extension increased your privacy by blocking all 3rd party tracking codes and several advertisements on each site.

That’s the power of browser plugins! They can do just about anything you can imagine and more.

What’s your favorite browser plugin?
