What SponsorBlock does

SponsorBlock is a browser extension published by Ajay (SponsorBlock). The official listing describes its purpose as: “Easily skip YouTube video sponsors. When you visit a YouTube video, the extension will check the database for reported sponsors and automatically skip known sponsors. You can also report sponsors in videos. Other browsers: https://sponsor.ajay.app” 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.

SponsorBlock is available through the official Chrome 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 a YouTube video and let SponsorBlock check its crowdsourced database for submitted segments.
When a known segment is reached, the extension can skip it and show a notice that allows the action to be undone.
Open the popup or settings to choose which categories are skipped automatically, shown with a button or left untouched.

How to install SponsorBlock

Open the official store icon for the browser you currently use: in Chrome choose Add to Chrome; and in Firefox choose Add to Firefox. Confirm that the title is SponsorBlock and the developer is Ajay (SponsorBlock), then read the permission dialog before accepting the installation.

After installation, open the browser’s Extensions menu and pin SponsorBlock 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: Ajay (SponsorBlock).
Use only the official Chrome and Firefox links recorded above.

First-use workflow for SponsorBlock

The safest way to learn SponsorBlock 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 a YouTube video and let SponsorBlock check its crowdsourced database for submitted segments. When a known segment is reached, the extension can skip it and show a notice that allows the action to be undone. Open the popup or settings to choose which categories are skipped automatically, shown with a button or left untouched. To contribute, mark the start and end of a segment, select the correct category and review the timing before submitting. 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.

Documented features and settings

SponsorBlock lets you skip over sponsors, intros, outros, subscription reminders, and other annoying parts of YouTube videos. SponsorBlock is a crowdsourced browser extension that lets anyone submit the start and end times of sponsored segments and other segments of YouTube videos. Once one person submits this information, everyone else with this extension will skip right over the sponsored segment.

Practical use cases for SponsorBlock

Use SponsorBlock 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.

Begin with one representative page or task.
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

SponsorBlock is an open-source community project and the extension listing does not require a paid subscription. Donations to the project are separate from extension access.

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 6.1.7 and update timestamp 2026-07-13T16:56:51Z. It declares or requests access including: storage, scripting, unlimitedStorage, https://sponsor.ajay.app/*, https://*.youtube.com/*, https://www.youtube-nocookie.com/embed/*. 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.

Segment timing and categories are crowdsourced, so an incorrect submission can skip wanted content. Use the undo or voting controls when a segment is wrong instead of assuming the video itself is incomplete. Custom third-party YouTube front ends may request additional site access. 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.
