Finally the Answer to Installing and Using Extensions in Chrome

I think this is as clear an explanation of extensions as I'v seen, it is to me anyway :-))

I won't go into where to create your extensions folder, I have mine in the Chrome default location (C:\Users\Steve\AppData\Local\Google\Chrome\User Data\Default\)

For this example I'll use AdSweep as the extension to be installed (The paths are fairly straightforward).

Copy the AdSWeep.crx file to your preferred location

You then need to install it, there are 2 options

1. Create an installation shortcut ...

Very simply add "--install-extension" after the Chrome.exe and the name of the file you want to install at the end of the path

C:\Users\Steve\AppData\Local\Google\Chrome\Application\chrome.exe --install-extension="C:\Users\Steve\AppData\Local\Google\Chrome\User Data\Default\Extensions\adsweep.crx"

2. Click (or double click) on the file in your extensions folder.

The effect of either of these options is to create a folder in your extension folder which contains the manifest.JSON and AdSweep.js files

To run Chrome with extensions enabled is really easy just add "--enable-extensions" after the Chrome.exe in your Chrome shortcut.

C:\Users\Steve\AppData\Local\Google\Chrome\Application\chrome.exe --enable-extensions

That's it, this article (although its about AdSweep probably explains it better than me).

If you want to check your extensions are installed then chrome-ui://extensions/

I think it was Kyrax who was pondering the problem of multiple manifest files in the extensions folder, taking this as an example 'cos I've actually got 2 extensions live then all you do is put the JSON and JS files in a folder ...

Anyway,

Enjoy people :-D

Just for completeness ...

You can have Extensions and User Scripts enabled at the same time ...

So bring 'em on, Extensions and User Scripts :-))

OK guys, I converted my YouTube HQ/HD Download Helper into a USER SCRIPT!

http://blackcoil.com/youtube.user.js

I assume you all know how and where to install a user script. Once you install this in your "User Scripts" folder, anytime you navigate to a page matching:

http://www.youtube.com/watch*

the script will figure out what is the highest quality video possible, and will force it to load by redirecting to a URL with the "fmt=" attached.

The script will also add a textbox to the right of the video that will contain a nicely formatted file name:

username - video title.mp4

When you click the box, the file name will highlight. Just press CTRL-C, then click the SAVE link to the right of the textbox. Your "Save File As" box will pop up, and just CTRL-V the nice file name in place of the default "video.mp4" and done! You're downloading the highest quality version possible of the video you're watching, and it's named intelligently!

The script also adds a link to the "All Videos for the User" page under the textbox, since there is no way to get there from the default YouTube video page.

I'll improve this more this weekend. Let me know how this script works for you.

Enjoy!

Francesco,

It works great. This is by far the most useful Youtube download script I have ever used.
It replaces now my previous one who used a third party site to download the video.
Work great as a user script also.
Thanks a million, great job.

Great job !

It works unbelievably well, and it doesn't crowd the whole video with a huge DOWNLOAD button.. Thanks alot!

Francesco,

Do you know this site: http://songza.com/
Songza is based on extracting audio from Youtube and others.
Can your script be modified to work with Songza?
I think you would hit world news if that where possible.
Just a thought...

I've read with interest this thread about downloading YouTube videos

As I'm new to things like extensions and user scripts I thought I'd try what seemed like the easiest and downloaded the user script

It seems to be working because I'm getting HQ videos being loaded, what I'm not getting is the text box

Where exactly is it supposed to be and have you got a link to something that show me what I should be getting

I cant get this user script to work.... (and another script as well)

this is what I have
my target
“C:\Documents and Settings\beabrams\Local Settings\Application Data\Google\Chrome\Application\chrome.exe” -enable-user-scripts

and the script is called youtube.user.js located in the
C:\Documents and Settings\beabrams\Local Settings\Application Data\Google\Chrome\User Data\Default\User Scripts

any other ideas… and I typed it out on the target and didnt copy and paste

Your shortcut and paths look correct to me. Maybe you got a bad version of the file? Try downloading a fresh copy:

Also, make sure you're on the DEV channel? If you ARE, your Chrome version should be 2.0.174.0 right now.
