Introduction
As an avid user of Google Chrome and other popular web browsers, you might have noticed that some extensions continue to run even after closing the browser. This raises the question of whether the extension background script stops running when closing the browser or not. In this article, we will explore this topic in detail and provide a comprehensive answer to this question.
What is an extension background script?
Before we dive into the main topic, it is important to understand what an extension background script is. In simple terms, it is a JavaScript file that runs in the background of the browser and performs tasks that the user may not be aware of. For example, an extension that checks for new emails in the background or updates a webpage without user intervention will use a background script.
How do background scripts work?
Extension background scripts are designed to be persistent and continue running even when the browser is closed. They start running when the extension is installed and stop running only when the extension is disabled or removed. They run independently of the browser UI, meaning that the user does not have to interact with the extension for it to continue running.
Does the extension background script stop running when closing the browser?
The answer to this question is no. Extension background scripts are designed to continue running even after the browser is closed. They will only stop running when the extension is disabled or removed from the browser. This allows extensions to perform tasks in the background even when the user is not actively using the browser.
How does this affect performance and battery life?
Extension background scripts can have a significant impact on performance and battery life. This is because they continue running even when the browser is closed and consume system resources. If you have multiple extensions with background scripts running, it can slow down your computer and reduce battery life.
How can you disable extension background scripts?
If you want to disable extension background scripts to improve performance and battery life, you can do so by following these steps:
- Open the browser and go to the extension settings page.
- Find the extension you want to disable and click on the “Details” button.
- Scroll down to the “Site access” section and toggle the switch next to “Run this extension in the background” to the off position.
- Close the settings page and restart the browser.
Conclusion
In conclusion, extension background scripts continue running even after the browser is closed. This allows extensions to perform tasks in the background without user intervention. However, this can also have a significant impact on performance and battery life. If you want to disable extension background scripts, you can do so by following the steps outlined above.
