In previous versions of FF and in other browsers, I can use the tab key to navigate through all the links on a webpage - I can't seem to do this with FF5, the tab key will only highlight the address bar, search bar, and any form fields within a webpage. Using the tab key to navigate through links on a page is an accessibility feature, and I often use it to show hidden skip links at the top of a webpage for users who prefer to use the keyboard over a mouse and for assistive technologies. Is this something that can be turned back on in preferences? Or is there a reason why it was removed from this version?
