What is an add-on and what does it do?
Every browser can have its features expanded with add-ons. This allows the browser to be tailored precisely to your own needs by retroactively adding in features that the browser doesn’t normally have.
What are add-ons used for?
The following types of add-ons are the most popular at the moment:
- Language support, such as Google Translate, Grammarly, etc.
- Ad blockers such as AdBlock Plus or uBlock origin
- Online conference features such as Cisco Webex, Skype, Google Hangouts, etc.
- Social media tools, such as for Instagram, Pinterest, or others
- Video downloaders
- Website screenshot tools such as Fireshot, Evernote Web Clipper, etc.
- Password managers such as LastPass
Browser add-ons are usually called “extensions”, but this depends on the browser. They come from independent developers and are offered in browser-specific online stores.
Add-ons are small programs that expand or extend the features of a browser.
Where can you find browser add-ons?
In Chrome, add-ons are called “Extensions”. You can get Chrome to show you your installed extensions by typing the following in the address bar:
What’s the difference between an add-on and a plug-in?
Strictly speaking, add-ons are a subtype of plug-ins, which are small programs that give extra features to the main program.
For browsers, however, a key difference exists between add-ons and plug-ins: plug-ins are compiled programs (executables) that are linked to the browser using an interface. Well-known examples of this are Adobe Flash Player or the Java plug-in. Many browsers provide support for plug-ins and will only allow add-ons or extensions to run if they work with standardized interfaces (APIs) and were programmed using strict, pre-defined standards and safety rules.
