Why do some extensions require access to all data on visited websites, and how can risks be minimized?

An extension requesting broad permissions to read and change data on all websites often causes justified concerns among users. Technically, such permission allows an add-on to analyze the content of any open web page, intercept typed characters, modify the appearance of interfaces, or embed third-party advertising and analytics trackers into your browsing session.

However, far from every extension requesting such rights has malicious purposes. This level of access is vital for the operation of text translation tools, grammar assistants, interface themes, password management systems, and comprehensive ad blockers. Without the ability to inject their code inside loaded pages, these programs simply would not be able to perform their core functions.

To protect yourself while still using the necessary tools, it is recommended to follow a number of digital hygiene rules:

Modern browsers provide flexible control tools that allow switching the data-reading permission from continuous operation mode to on-request mode. This means the extension will not be able to run in the background unnoticed by you, and will only gain access to the page after you click its icon on the toolbar.
