Replace google.* with google.tld in the list of includes. It's also a good idea to explicitly list the URL patterns related to your script. *.google.* is too general.

Or just add a new filter in AdBlock Plus:
http://talkgadget.google.com/talkgadget/notifie...*

Thanks for implementing some of my suggestions. It would be nice to somehow store the address book locally and refresh it every x hours/days, but the current implementation is pretty good.

For Google Apps, the URL is: https://mail.google.com/a/EXAMPLE.COM/contacts/... .

Other suggestions would be to add support for multiple addresses separated by commas and to no longer change the title of the script (it's installed as a new script).

Some suggestions:
1) improve the excluding pattern: http*://*.google.com/*, http*://google.com/*
2) increase the delay for hiding the suggestions. They disappear way too quickly. A better idea is to hide the list only when you click somewhere in the page.
3) Only match prefixes: if I type "ne", don't match janet because it doesn't start with "ne". Learn from Gmail's autocomplete feature.
4) Don't use the CSV file. Try this XML file: http://docs.google.com/c/data/contacts?max=1000
5) Stop highlighting names when you are only matching email addresses.
6) Start to match names. They are more important than email addresses.

It does work, at least for Opera 9.5. You should know that the script shows a popout link next to the embedded YouTube videos, not next to the videos displayed at youtube.com.

The script should now work in Opera and the popout link should look better.

I also suggest removing the last if, which is unnecessary and prevents the replacement of the favicon in iGoogle. Another subdomains that should be excluded: http://docs.google.com/*, http://spreadsheets.google.com/*, http://sites.google.com/*, http://pages.google.com/* + the https versions.

You should replace .com with .tld in your includes to also allow international domains (all people outside US are redirected to local domains). You should also exclude these sites because they have custom favicons: http://www.google.com/calendar/*, http://www.google.com/reader/*, http://picasaweb.google.com/*, http://pack.google.com/*, http://toolbar.google.com/*, http://desktop.google.com/*, https://www.google.com/health/*, http://www.google.com/notebook/*, http://webaccelerator.google.com/*, http://groups.google.com/*.

@rkn8r:
It's not necessary to do that. All YouTube videos are displayed at: youtube.com/watch?v=*.

@atr3yu_junky:
You need a video player that is able to play MPEG-4 videos. Try VLC ( www.videolan.org/vlc/ ), it's one of the best video players you'll ever find and it comes with most popular codecs. Other players: iTunes, QuickTime, Winamp, MPlayer etc.

Here's an idea: show the lyrics box only if the video is in the Music category or expand the box for music videos.
