BYTubeD–Bulk Youtube Video Downloader Add-on for Firefox

There are several Firefox add-ons that allow you to download videos from YouTube. However, you can only download one video at a time i.e. only the active video on the page. This is where Bulk Youtube Downloader comes to the rescue.

Bulk Youtube Downloader can be used to grab all links to Youtube videos from a webpage and download all the videos at once. This works well on the Youtube homepage, channels, playlists and single video pages where you can not only play the video but also download all other related videos.

To download Youtube videos all at once, right-click on the page and select the “Bulk Youtube Video Downloader” context menu entry. Alternatively, you can also run the add-on from the Tools menu.

Bulk Youtube Downloader displays all Youtube videos in its interface. You can select the videos to download by using the mouse or selecting them all with CTRL A. The video downloader will download the videos and save them in the FLV format to your disk. You can also download in mp4 format if you want.

You can select the download destination and use filters to filter out some of the videos. By clicking on the start button you can transfer all selected videos to the download queue of the web browser from where they will be downloaded to the disk.

Bulk Youtube Downloader is especially useful for downloading playlists from Youtube but can also come in handy for channels and other themed video pages.

Bulk YouTube Video Downloader is available for all Firefox 3.x browsers.

Mozilla is requesting developers to help it in testing a new security tool for its Firefox web browser. Firefox is already much stable and secure when compared to Internet Explorer. The new security tool will boost its security further.

Mozilla has made available a preview build for Content Security Policy (CSP). Webmasters and developers can download this and try it out for themselves.

CSP prevents web pages from getting infected from hacking-attacks such as cross-site scripting. It allows webmasters to put restrictions on how outside websites can access and interact with the web page.

CSP has been under active development since the last several months and is now be available with the preview builds of Firefox so that developers can test it in real-time production environments.

The tool has already received a positive response from other browser vendors, webmasters and security researchers. Webmasters and developers have welcomed the move and praised its design. Mozilla encourages server admins and webmasters to download the preview Firefox build and test the new features for themselves.

CSP is still in developmental stages and so we cannot expect it to be fully functional. It may have some bugs and stability issues. However, when the tool comes out of the developmental stage and becomes available to the general public, we can expect better security while surfing websites.

Mozilla Firefox is the world’s leading open source web browser. It is the world’s second most popular browser–not because the leader–Internet explorer is better but because it has Microsoft’s marketing muscle to back it. Firefox is much stable and more feature-rich when compared to IE. Mozilla is constantly trying to improve the user interface, engine and features of Firefox.

Now Mozilla has turned to a surprising source for inspiration–Microsoft. It is now switching to Microsoft’s “Ribbon UI”. A note in the developers’ wiki at Mozilla.org reads, “Starting with Vista, and continuing with Windows 7, the menubar has been systematically removed from Windows applications built by Microsoft and other vendors. It has been replaced with alternatives like the Windows Explorer contextual strip or the Ribbon found in Office 2007. The Ribbon UI is now also used in Paint and Wordpad for Windows 7.”

Mozilla is not making the switch to the Ribbon Interface. However, it will adopt a similar approach to clean up and improvise its existing menu. The new interface will provide the user more space which will be beneficial especially for netbook users. The new interface will integrate the Windows Aero Glass effect to the entire controls strip. Currently, this feature works only in the frame.

Currently, Firefox is not as polished as Mozilla expects it to be. In its development notes, Mozilla states that, “Firefox feels dated and behind on Windows. Issues include the absence of Glass, anemic purple toolbar color on Vista, tall and bulky UI footprint, element overload, inconsistent toolbar icon usage/style, lack of a tactile look and feel and perhaps too great of a divergence between the look on XP and Vista/7.”

The new menu bar will be available in Firefox 3.7 which will be released in March 2010. Users who prefer the present version can switch to it by pressing the ALT key inside the Firefox frame.

Mozilla is not yet fully committed to the switch. It is open to suggestions. Mozilla states that “this direction is at the team proposal stage, to be approved by drivers and subject for constructive community feedback.”

Firefox 3.7 Nightly builds now include support for WebGL, indicating that the next major release will have full support for WebGL. Google Chrome and other browsers based on WebKit are not the only ones who are getting improved 3D-rendering capabilities as Firefox has followed suit.

Vladimir Vukicevic, the developer involved in the project said that WebGL is essentially a way to access OpenGL from within the browser using the new HTML 5 canvas tag. In combination with Javascript, which has made tremendous leaps in performance, WebGL can create a new dimension of 3D graphics on the web.

Despite progress in key areas, there are still many issues that need to be resolved before WebGL become available for everyday use. WebGL still has security and portability issues. In addition, some platforms do not have support for OpenGL and so WebGL will not work on them. Simple demos demonstrating the capabilities of WebGL will be available in the very near future.

The Firefox nightly build (Minefield) can be downloaded from the Mozilla FTP.

To enable WebGL support, type about:config in the address bar and change webgl.enabled_for_all_sites from false to true.
