Downloading videos from youtube or any other video sharing sites such as Metacafe, Veoh, Revver, Myspace etc is very easy with these firefox extensions. If Firefox is already your default browser, then having one of these extensions installed will help you save your favorite videos for later viewing.
How To Download FLV and SWF Videos
Apart from being a web developer’s must have tool, firebug can help you spot everything that’s being downloaded/retrieved from the WWW in Firebug’s NET panel. As can be seen from the image above, it’s very easy to tell what the video file is since it’s the one with the largest filesize most of the time. Once you know that, you can simply copy the file’s location and paste it in your download manager to be downloaded. Get firebug here.
DownloaderHelper, like its name implies, helps you in downloading a lot of the other stuffs apart from video. The unique feature I like is it displays all the options for users to download High Quality (HQ) videos or a normal (low) quality video regardless of what quality you’ve selected to play a video on youtube. Other extension such as Firefox and NetVideoHunter will only show you the download location of the video for the quality that you have selected to view. Get downloadhelper here.
I tried NetVideoHunter as it was getting quite popular in terms of download counts. It’s supported with ads but still does its job of grabbing the download location for the video you are viewing. Download NetVideoHunter here.
