"...and bumpity-bumpity-bump came the maxVersion..."
CustomizeGoogle is now 1.4.0a-ready.

Updated CustomizeGoogle to have a maxVersion of 1.3.0a for the 1.2 release and/or 1.3 testing.

Broken version numbering? Is 1.2 less than 1.2.0a?

Compatibility up to Songbird 1.2.

Added : 'Query Suggestions' in Sticky Preferences.
Bugfix: [Web -> "Add links to bookmark" -> "Firefox"] is now working again.

Update: Restored links to other search engines in Google Shopping

    Note : Enabling both 'Google Suggest' and 'Query Suggestions' at the same time is not needed. That should however not make any difference to the user experience.
Note : If you don't want suggestions at all and disable 'Query Suggestions' at google.com/preferences or in 'Sticky Preferences'. Then don't forget to disable the 'Google Suggest' option in CustomizeGoogle.
