UPDATE (5th March 2017): We fixed an issue where clicking Download results in "Failed/Forbidden" instead of downloading the video. The online downloader is now 100% Working. If you're still encountring any issues, please contact us any time. We are also working on a fix for our Chrome extension since it's not detecting some videos... Thanks for your patience.
UPDATE (18 February 2017): We fixed some issues related to videos that include subtitles.
UPDATE (3 February 2017): We updated our Chrome Extension and now it is working on all Facebook videos (including private videos). The extension should be updated automatically, if not please remove it and install it again from HERE. Thanks for the issue reports, if you are still encountring any issues, please Contact us anytime.
UPDATE (4 January 2017): We noticed some videos are not being detected by our Chrome Extension, we are working on a fix and the extension should be updated in the next few days. Thanks for your patience. In the meantime you can keep using the Online Downloader (above) like usual.
