Article in English: If you have Firefox installed on your computer, you can use it to look for a downloadable video on a page; this can save you time when trying to find and download the video:  Open Firefox. Go to the website on which your Flowplayer video is hosted. Play the video if it doesn't begin playing. Right-click (or Control-click on a Mac) a blank place on the page. Click View Page Info in the drop-down menu. Click the Media tab. Scroll through the results, looking for a "Video" option in the "Type" column. If you see a video listed on the page, you can proceed with the rest of this method; if not, you most likely can't download the video. Click or double-click the Chrome app icon, which resembles a red, yellow, green, and blue sphere. This extension allows you to download quickly any Flowplayer videos which aren't encrypted. vGet won't allow you to download videos that are otherwise impossible to download. It's a blue button in the upper-right side of the page. Doing so installs the vGet extension in Google Chrome; you should see the vGet app icon, which resembles a downward-facing arrow, appear in the upper-right side of the Chrome window. This should be the website on which the Flowplayer video that you want to download is located. The vGet extension sometimes requires you to begin video playback in order to find the video on the page, so make sure you click the video's "Play" button if necessary before you proceed. It's the downward-facing arrow in the upper-right side of the Chrome window. A drop-down menu will appear. If you don't see this icon, first click ⋮ in the top-right corner of the Chrome window, then click the "vGet" icon near the top of the drop-down menu. You should see at least one video's name in the drop-down menu; clicking it will prompt the video to begin downloading onto your computer.  If you don't see any videos listed here, your video can't be downloaded. Depending on your Chrome settings, you may have to select a save location before you can proceed.
