Opt-Out to Google Analytics
Google has answered the requests and feedback from privacy groups and privacy-conscious users by creating the Google Analytics Opt-out browser add-on for Firefox v3.5 and higher, Internet Explorer v7 and v8 and Google Chrome 4.x and higher. Use the said add-on to turn off Google Analytics in Firefox and other supported browsers. It is currently in beta phase but it works to stop being tracked by websites that uses Google Analytics.
Please note that this add-on does not stop or remove Google Analytics scripts in all websites you will be visiting but it prevents the script from sending information to the Google Analytics server.
If you need to deploy or install the said add-on for Firefox, simply visit the link below to download and save in a safe place on your hard-disk or flash drive. It's best to visit the add-on site of Google Analytics to get the current version though, since another may be released.
All you have to do is to visit this webpage in Google using IE, Chrome or Firefox and download the add-on:
Accept the Terms of Service to install the add-on then Firefox will show a prompt, asking if you will allow the installation of the add-on:
Moving forward, Firefox should display the prompt that it prevented the installation of the add-on. Simply click "Allow" button to proceed with the install:
If the download is not interfered with and the installation is successful, you will just need to restart Firefox. As usual, a restart is needed when installing any Firefox add-on. ( I wonder why Mozilla can't enhance this process by allowing add-ons to be used at once without the need of a restart!)
When done, you should see the add-on in Firefox Add-on Manager. This manager allows you to either enable or disable the add-on.
