English, French, Arabic, Spanish, German, Portuguese, Chinese (Simplified), Japanese, Korean, Hindi, Russian, Italian, Dutch, Turkish, Polish, and 44 additional languages.

## Extension permissions

When you install Video Downloader Plus, the browser asks you to approve a set of permissions. Here is what each one is used for:

| Permission                      | Purpose                                                                                                                                                                                  |
| ------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **tabs**                        | Associate detected streams with the correct browser tab, update the detection badge when you switch tabs, and clean up stream data when a tab is closed                                  |
| **Network monitoring**          | Watch for video streams (HLS, DASH, MP4) as pages load by analyzing response types and URL patterns                                                                                      |
| **Download rules**              | Manage reliable file saving and streaming player header routing                                                                                                                          |
| **storage**                     | Save your preferences, detected stream data for the current session, and authentication state locally on your device                                                                     |
| **downloads** (optional)        | Enable saving files through the browser's download dialog with proper file names and folder routing — this permission is only requested when you turn on download management in settings |
| **all\_urls** (host permission) | Detect video streams on any website — required because video content can be hosted on any domain, not just a fixed list of known platforms                                               |

<Info>
  Page URLs may be sent to Video Downloader Plus servers on certain websites where network-level interception alone cannot identify streams. This is used exclusively for fallback stream detection.

## Why Chromium only?

Video Downloader Plus relies on a set of browser APIs that are currently stable only in Chromium-based browsers:

* **Real-time network monitoring** — Identify streams the moment they load on a page
* **Declarative download rules** — Reliable file saving that works across all sites
* **Synced settings** — Preferences that follow you across browser profiles and devices
* **Background processing** — Lightweight event-driven architecture that stays responsive without draining resources

Firefox exposes some equivalent APIs through the WebExtension standard, but the behavior diverges enough that a separate implementation is required. Firefox support is currently in development.
