The icon becomes animated if there is some content available for download on a website. You can click on ‘down arrow’ right of the icon and select the video/audio you want to download.

In case multiple-streams of same video (usually of different quality) are available it will show you an option to download any one of them. This feature is especially useful for quickly browsing through your videos in Low Quality mode but downloading the high quality video for later viewing.

Clicking on the chosen video will download that video to the default location.

Further the addon also make some commonly used tasks after video download easier. It gives user the option to get the raw URL of video which can be plugged into other softwares, to tweet the video to their twitter account, to convert the video after downloading & to secure the videos with the password on local drive. The last two options require two separate addons from the same developer.

As a last feature, the Downloader Helper also features a list of sites ,along with their ratings, from where free videos are availalble. You can get this list by clicking on the icon itself.

Download DownloadHelper Extension for Firefox

Until, now Firefox was using the concept of themes which I thought I thought was pretty neat. But I always wondered, if I could just change the themes on the fly and don’t have to restart my browser all the time. Seems like someone was listening. Firefox now has an extension that does exactly this. Don’t believe me, take a look for yourself. All you’ll need is persona, a firefox extension that changes the theme on the fly. Let’s see what’s the philosophy behind buying this concept.

Personas for Firefox is a extension that adds lightweight theming to your browser. It’s an experiment in personalizing.

Personas builds upon the ideas that:

themes today are too hard to find, install and use

graphic designers should be able to style the browser without having to code

browsers can be more than just desktop software, they can include online components

people just want their computer to be a little more fun and personal

Hmm, seems pretty intriguing and the whole argument seems to be pretty strong to be questioned for a defense. And actually the extension seems to be fun and I am sure you’ll enjoy it. The best part is all changes to the browser chrome are applied instantly, with no need to restart.

Take a look at some the personas below:

I am sure you are going to fall in love with this extension.
