Chrome extensions that don't read your page content
"Read and change all your data on all websites" is the default permission request for most Chrome extensions. It's worth understanding what that actually means — and knowing there are alternatives.
What Chrome extension permissions actually mean
When you install a Chrome extension, Chrome shows you what it's requesting access to. The most common and most broadly scoped permission is "Read and change all your data on all websites" — sometimes called "host permissions" in developer terms.
This permission allows the extension to:
- Read the content of any page you load (including your banking dashboard, your email, form fields you type into)
- Modify what you see on any page (add elements, remove elements, change text)
- Run in the background as you browse, logging activity if the extension is designed to do so
For extensions that genuinely need to interact with page content — ad blockers, password managers, reading mode tools, web clippers — this permission is necessary. There's no way to block ads or clip content to a notes app without being able to read and modify the page.
But many productivity extensions don't need this capability at all. A to-do list, a bookmark manager, a tab timer, a pinboard — these tools work with browser data (your bookmarks, your tabs, local storage) rather than with the content of pages you visit. There's no reason they need to read what's on your banking page.
The reason many request it anyway: broad permissions are the default in many extension templates, and developers often don't restrict permissions to only what they need.
The Cool Easy approach
Every extension in the Cool Easy lineup was built without host permissions — the "read and change all your data on all websites" permission is absent from all of them.
Here's what each one actually uses:
Easy Todo Note — storage, alarms, notifications, sidePanel. It stores your to-do list locally, sets timer alarms, and shows browser notifications when timers end. It doesn't need to know what pages you visit.
Easy Tab Focus — tabs, storage, alarms, sidePanel. It reads tab titles and URLs (to show you what you've been focused on) and tracks time in the browser's foreground tab. No page content — just tab metadata.
Toolbelt — storage, sidePanel. Image resizing, CSV viewing, and formatting utilities all happen client-side in the extension's own context. No host permissions needed.
Easy Bookmark Manager — bookmarks, storage, sidePanel. It reads and writes your Chrome bookmarks via the bookmarks API. It doesn't need to read pages at all.
Job Pin Board — tabs, storage, sidePanel. When you pin a job, it reads the current tab's title and URL (tab metadata, not page content) and stores the pin locally.
Browse & Pin Buddy — same as Job Pin Board. Tab title and URL from the browser API; nothing extracted from the page itself.
How to check any extension's permissions
Before installing an extension:
- Go to the Chrome Web Store listing
- Scroll down to "Privacy practices"
- Look at the permissions list
After installing:
- Go to
chrome://extensions - Click "Details" on the extension
- Check the "Permissions" section
Red flags worth noting:
- "Read and change all your data on all websites" for a tool that doesn't interact with page content
<all_urls>in the permissions (equivalent to the above)- Remote code execution permissions
- Permissions that don't match the stated functionality
Extensions that legitimately need host permissions
To be clear: needing host permissions isn't inherently suspicious. These categories of tools require it to function:
- Ad and tracker blockers (uBlock Origin, Privacy Badger) — need to intercept and block network requests on every page
- Password managers (Bitwarden, 1Password) — need to detect and fill password fields
- Read-later and clippers (Instapaper, Notion Web Clipper) — need to extract page content
- Translation tools — need to read and replace page text
- Accessibility tools — need to modify page presentation
For these, the permission is appropriate and the trust question is about the developer's track record and business model.
The concern is when a tool that doesn't need to read page content requests the permission anyway — either by oversight or intentionally.

FAQ
What does "read and change all your data on all websites" actually mean?
It means the extension can inject JavaScript into any page you load, read the page's content (text, form fields, URLs), and modify what you see. For extensions that genuinely need this — content blockers, reading mode tools, web clippers — it's necessary. For tools that work with browser data rather than page content (bookmark managers, tab timers, to-do lists), it's an over-broad permission.
Are extensions with host permissions automatically dangerous?
No. Most popular extensions with broad permissions are trustworthy. The risk is that (a) a trusted extension gets acquired by a less trustworthy company, or (b) you install something that looks useful but is primarily designed to monetise your browsing data. Permissions don't tell you intent — they tell you capability.
How can I see what permissions an extension has?
Go to chrome://extensions, click "Details" on any extension, and look at "Permissions." You can also check the Chrome Web Store listing — the permissions are listed under "Privacy practices" before you install.
Can I revoke host permissions after installing?
Yes, with some limitations. In Chrome, you can click the extension icon, then the three-dot menu, and restrict permissions to "On click" or specific sites. Not all extensions function correctly with restricted permissions — check whether the core functionality still works.
