Share on:

From a noun to a verb, Google has become a core part of our daily lives, something we almost can’t do without. The company has dominated nearly everything from search to OS and keeps seeking growth opportunities.

To enhance web surfing experience, Google went on to create Google Chrome, which has become one of the fastest, safest, and overall best web browsers out there, with a controlling market share. 

While browsing the internet, users download files, stream videos, take screenshots, make notes, and perform a host of other activities online.

Extensions are basically software or programs designed to enhance such browsing experiences. It’s like having all the different software you need in one browser; or better yet, making your browser compatible with everyday applications in an all-in-one fashion. 

Some extensions help you block unwanted/unsolicited ads, download files, correct grammar, take screenshots, record audio, and video, etc. 

According to Google, Google Chrome extensions are smaller software programs that are designed to customize the user’s browsing experience. They allow users to tinker with and tailor Chrome functionality and behavior to taste. 

These extensions are built on web technologies such as HTML, CSS, and JavaScript.

Google Chrome extensions aren’t the only ones out there.
