Released Nov 12, 2026 - 347.19 KBWorks with firefox 142.0 and later, android 142.0 and laterv3.5.8 – Downloads behind protected CDNs work now: the page's Referer is sent with every playlist and segment request, including the redirect hop to the CDN host, so HLS downloads that used to fail with 403 finish and save as a normal video. Pages that advertise a video URL nobody can fetch now offer the file that actually plays. The popup no longer hangs on "Sniffing…" on pages whose ad frames never load.Source code released under MIT License

Version 3.5.1
Released Oct 12, 2026 - 323.13 KBWorks with firefox 142.0 and later, android 142.0 and laterWhat's new in v3.5.1:
- Firefox for Android is now supported. That browser has no downloads API, so a finished download opens in a tab where you tap the file link to save it, instead of being handed to a download manager. The folder settings do not apply there and are replaced by a line that says so.
- You now accept the Terms of Service before using the extension. On first install the welcome page shows the terms, and the popup stays locked behind a terms dialog until you accept. Nothing runs until you do.
- The full End User License Agreement and Terms of Service is bundled with the extension and readable offline: what the licence covers, the warranty disclaimer, the limit on liability, and the policy on refunds for the optional Pro licence.
- Clearer Pro pricing: the price is simply the price. The previous struck-through "was" price and the 50% off badge have been removed.
- The Pro licence is described accurately throughout: one-time payment, no subscription, valid for as long as the extension is available.
- Updated privacy policy with the data controller, legal basis, retention periods and your data protection rights.Source code released under MIT License

- You can now paste your Pro license key directly in that card ("Already have a license key?") — no need to open Settings.
- The Pro card now sits above the sponsored banner, so the offer is read first.
- Countdown and status text updated in all 6 languages, plus layout fixes for short popup windows.Source code released under MIT License

- Layout fixes: the sponsored slot can no longer be squeezed into an empty bar in short popup windows.Source code released under MIT License

Version 3.3.4
Released Sep 28, 2026 - 264.25 KBWorks with firefox 142.0 and laterv3.3.4 - Better format and resolution support
Fixed a bug where many videos were never detected and could not be
downloaded: files served from /preview/ paths were wrongly treated as
thumbnails and skipped, so the best quality was often the one missing.- Real video files are no longer discarded for having "preview" in the path
- Direct download links (<a download>) are now detected
- All media on the page is found, not only what is scrolled into view
- AVI, MKV, FLV, MOV, 3GP, WMV, VOB and more recognised, not just MP4/WEBM
- The list is no longer truncated to three items
- Fixed corrupted translation files that could stop the extension loading
Preview depends on browser codec support: MP4/WebM play in-app, formats like
AVI or MKV download fine but cannot be previewed.Source code released under MIT License
