I came across this today hope this is the right place to post this. Looks like it has all the bells and whistle's. Any input as to why we should upgrade to this version. Also what do they mean "not recommended for drummers" hope that is not a stupid Q's,

is drummers literal?
Thanks
Mozilla has released Firefox 11, adding some new developer tools, support for the SPDY protocol and the ability to sync your add-ons between computers.
This release is not recommended for drummers, but everyone else can grab Firefox 11 from the official Firefox download page, or you can just wait for the automated update system to work its magic.
The big news in this release is the new add-on syncing tool. Firefox Sync has long handled syncing bookmarks, preferences, passwords, history and open tabs across computers, but until now syncing add-ons was an entirely manual process. Add-on syncing has been a feature request for Firefox Sync pretty much since syncing was announced in 2010, but until to day it wasn▓t available.
Firefox 11 also has some new features for web developers, including the Tilt 3-D code inspector. Derived from the Tilt plug-in, the 3-D code inspector is a WebGL-based visualization of the page▓s DOM and HTML structure. When you select ⌠inspect element■ Firefox will bring up a breadcrumb-style menu bar at the bottom of the page. In Firefox 11 you▓ll find that a new button ⌠3D■ has joined the HTML and Style buttons in the page inspector menu bar.
