What uBlock Origin does

uBlock Origin is a browser extension published by Raymond Hill. The official listing describes its purpose as: “A wide-spectrum content blocker that uses filter lists to block ads, trackers and other unwanted network or page content.” This guide combines verified store information, installation, first-use instructions, settings, browser support, permissions, privacy notes and troubleshooting so readers can decide whether the extension fits a real workflow.

uBlock Origin is available through the official Edge and Firefox stores linked on this page. Use those buttons instead of downloading an extension package from a third-party directory. Availability can differ by browser and can change over time, so a browser is shown only when a matching official listing has been recorded.

Open the toolbar popup to see blocked-request counts for the current page.
Use the large power button only when the current site needs to be trusted, then reload the page.
Use More and Less to reveal or hide the overview panel and advanced site information.

How to install uBlock Origin

Open the official store icon for the browser you currently use: in Microsoft Edge choose Get; and in Firefox choose Add to Firefox. Confirm that the title is uBlock Origin and the developer is Raymond Hill, then read the permission dialog before accepting the installation.

After installation, open the browser’s Extensions menu and pin uBlock Origin if its toolbar icon is hidden. Reload any tab that was already open before installation. Start on a non-sensitive page and verify the extension’s basic behavior before granting optional access, importing data or connecting an account.

Match the developer name: Raymond Hill.
Use only the official Edge and Firefox links recorded above.

First-use workflow for uBlock Origin

The safest way to learn uBlock Origin is to complete one representative task from beginning to end. Open the extension popup, dashboard or supported page, identify the primary action, then check what changed in the browser. Do not enable every optional setting at once because that makes conflicts harder to diagnose.

Follow this documented sequence: Open the toolbar popup to see blocked-request counts for the current page. Use the large power button only when the current site needs to be trusted, then reload the page. Use More and Less to reveal or hide the overview panel and advanced site information. Use the element zapper for a temporary removal or the element picker to create a persistent personal filter. These steps are based on the official listing, product site or project documentation recorded in the sources rather than on an assumption from the extension’s name.

Practical use cases for uBlock Origin

Use uBlock Origin for a task that matches its official purpose, then compare the result with the same task when the extension is disabled. This makes the benefit measurable and also reveals whether a page change, automatic action or saved data creates an unwanted side effect.

For work, research or important accounts, test with a copy or non-critical page first. Keep an independent backup when the extension stores passwords, tabs, scripts, filters or settings. Browser extensions can shorten a workflow, but they do not replace the original website, a backup or independent verification of an important result.

Change one setting at a time and compare the result.
Keep a backup when the extension stores important local data.

Free features, paid plans and accounts

The official project is free and open source. The project documentation says uBlock Origin is not an ad-funded product and does not require a paid account.

Pricing, account limits and platform support can change after this guide is written. Before paying or creating a business workflow, check the official website for current regional pricing, trial conditions, renewal terms, cancellation rules and the exact feature included in each plan. A donation link is not the same thing as a required subscription.

Confirm whether the feature you need requires an account.
Check current plan limits on the developer’s website.
Review renewal and cancellation terms before checkout.

Permissions, privacy and current version

The captured listing reports version 1.73.0 and update timestamp 2026-08-23. It declares or requests access including: access to page content required for filtering, storage for settings and filter data. A permission describes technical access, not proof of how data is used, so read both the browser prompt and the developer’s current privacy policy.

The power button changes filtering for the current site; it is not a global uninstall switch. Custom filters and advanced dynamic rules can break site functions, so change one rule at a time. The original uBlock Origin is currently listed for Edge and Firefox in this batch; do not install an unrelated similarly named Chrome copy. Use browser site-access controls when a permission is optional, and disable the extension temporarily when diagnosing a page conflict. Remove it if its current behavior, ownership or requested access no longer matches your needs.
