BilibiliSponsorBlock (小电视空降助手) is a GPL-3.0 browser extension for Chrome, Firefox, Edge and Safari that automatically skips crowd-annotated sponsored segments and other marked sections inside Bilibili videos, built for Bilibili viewers who are tired of sponsor reads and soft advertisements interrupting what they are watching.

What it is

BilibiliSponsorBlock is a TypeScript browser extension ported from SponsorBlock, the community segment-skipping project created by ajayyy. It keeps most of the upstream user interface and interaction model, then adds features specific to Bilibili, including the ability to bind re-uploaded ("搬运") videos so their segment information can be pulled automatically from the SponsorBlock database. Segment data is not generated by the extension itself: all marked segments come from viewer submissions, and the project publishes a leaderboard at https://www.bsbsb.top/stats/ so contributors can see how much time has been saved in aggregate.

The concrete problem it solves is that sponsored reads appear in the middle of Bilibili videos, often discovered only after watching half the clip. The extension fetches segment timings and jumps past them automatically, and it extends that behaviour beyond advertising to opening and closing animations, "一键三连" reminders, and a direct jump to the video cover position. In effect, it replaces both the manual scrubbing a viewer would otherwise do and, for Bilibili users specifically, the upstream SponsorBlock extension whose language coverage, mobile H5 support and third-party mirror support are not tailored to this platform.

Key capabilities

• Skips sponsor segments automatically, and also handles other categories such as opening and closing animations, "一键三连" prompts, and a jump to the video cover position.
• Relies on crowd-sourced annotations: viewers submit their own segments, and the project exposes a public leaderboard and aggregate statistics at https://www.bsbsb.top/stats/.
• Binds re-uploaded videos so segment data is retrieved automatically from the SponsorBlock database.
• Ships to the Chrome Web Store under extension ID eaoelafamejbnggahofapllmfhlhajdd and to Mozilla Add-ons as bilisponsorblock.
• Provides unpacked builds, ChromiumExtension.zip and FirefoxExtension.zip, for Chromium-based browsers including Edge and 360, and for Firefox.
• Packages a Safari Web Extension through npm run build:safari:macos, which generates a safari/ Xcode project and accepts BSB_SAFARI_APP_NAME, BSB_SAFARI_BUNDLE_ID and BSB_SAFARI_PROJECT_DIR overrides.
• Publishes a documented API in the project wiki, with a test video BV14741127BN, plus a downloadable segment database at https://download.bsbsb.top/database.zip.

Who uses it and how

• Everyday Bilibili viewers on desktop Chrome, Edge, 360, other Chromium-based browsers, or Firefox, who install it once and let it skip segments on every video.
• Community contributors who mark segments themselves, with the leaderboard at https://www.bsbsb.top/stats/ tracking submissions and total minutes saved, and per-user active-user figures served from bsbsb.top/api/getTotalStats.
• Developers building second-party tools from the public API or the full database download, which the README explicitly opens up for redevelopment.
• Safari users on macOS, who must build the extension from source and run the generated Xcode project before enabling it in Safari settings.
• Community members who coordinate through the Telegram group at https://t.me/bsbsb_top, since the project is maintained by one person in their spare time.

Getting started

Install from the Chrome Web Store or Mozilla Add-ons, or download ChromiumExtension.zip or FirefoxExtension.zip from the GitHub Releases page, enable developer mode in the browser's extension manager and load the unpacked folder. Safari users copy config.json.example to config.json, run npm ci, then npm run build:safari:macos and open the generated safari/ project in Xcode.

How it compares

Among the tools named here, the direct reference point is SponsorBlock, from which this project is ported and with which it shares most core functionality and interaction. The deliberate differences are scope reductions rather than additions: multi-language support is dropped in favour of Simplified and Traditional Chinese only, mobile H5 web support is dropped, and third-party mirror site support is dropped, while binding of re-uploaded videos and a refreshed UI are added. No list of paid products this project replaces is given in the supplied facts.

When to use it — and when not to

Choosing this extension means accepting a Chinese-only interface and a feature set that intentionally leaves out mobile H5 support and third-party mirror sites, so anyone who needs those should look at the upstream SponsorBlock instead. Development rests with a single maintainer working in their spare time, and the README states that a video usage guide is still only planned, so users who depend on thorough English documentation may find the project thin. The licence is clear and the repository is actively pushed, but the project's own notes frame it as a personal, hobby-maintained effort rather than a staffed product.
