Firefox has released Beta 11 of Firefox 4.0. Recently confirmed by Mozilla, there will be 12 Betas total. If you have not updated lately and are a Firefox 4 Beta User then I suggest you do. It usually takes a few days for all of Mozilla’s download mirrors to update, but you should be able to get it now.

You can download Firefox 4.0 Beta 11 here. If the download doesn’t load or redirects to a “Page Not Found”, go back and try again. There are literally a ton of different mirrors that the page will automatically try to pull from and not all of them are updated.

Despite Mozilla claiming that they will not “add” anything… they went ahead and did. In this new iteration you will find a “do not track” option. You can find this capability and enable it by going to the “Advanced” screen of Firefox’s Options.

As you know, this has been a very hot topic lately because advertisers and publishers are worried that they will receive less income as a result. This essentially stops ads from finding how what other sites and items you might have visited, prompting ads related to you.

Personally, as long as this is not enabled by default, people who would go out of their way to find this option are more than likely to have an ad blocker anyway.

What is new in Beta 11

• Support for the proposed Do Not Track (“DNT”) header
• Connection status messages are now shown in a small overlay
• WebGL has been re-enabled on Linux
• The default homepage design has been refreshed
• Firefox no longer switches into offline mode automatically
