What it actually reaches
Lets the extension inject JavaScript and CSS into web pages. What it can reach depends entirely on the host permissions alongside it: paired with a single site it touches only that site, paired with all sites it can read and rewrite every page you open.
Why an extension would ask for it
Any extension that changes how a page looks or behaves needs it — dark modes, ad blockers, form fillers, price comparison tools. The permission worth reading next to it is always the host list.
How to judge it
A permission on its own says little. What matters is whether it fits what the extension is for: a note-taking tool that reads every page you visit is worth a second look, while an ad blocker that does the same is doing its job. Read the permission next to the extension's stated purpose, and check the host list beside it.
