Hi Folks,

1. For online bookmarking ie Delicious/Google bookmarks drag the delicious or Google bookmark 'bookmarklet' to your 'Chrome bookmarks bar'

Delicious - http://delicious.com/help/bookmarklets
Google Bookmarks - http://www.google.com/support/chrome/bin/answer.py?answer=100215&topic=14680

2. For adblocking try the 'mvps.org' hosts file or privoxy available at http://privoxy.org'

3. For disabling javascript launch chrome with this parameter '-disable-javascript'. You can add this either in the shortcut or launch from the run command - for instance for XP:

C:\Documents and Settings\%username%\Local Settings\Application Data\Google\Chrome.exe” -disable-javascript

(The username will be different for your machine and path will be different for Vista)

Here are a couple of other parameters that work:

-disable-images
-disable-java
-disable-plugins
-disable-popup-blocking
-start-maximized

Got the noscript trick from a commentator 'Ionut Alex Chitu' at Google Chrome Tips
