Firefox 13 boasts a New Tab page that shows thumbnails of recently viewed websites, but it displays both regular and encrypted content, raising fresh privacy concerns for some users. One user told The Register that the thumbnails contained banking and email information from an earlier session, and even though this information is not transferred of stored outside of the browser, it is still an obvious security concern for those working on a shared computer. Mozilla has promised a patch — but did not say when it will be available — and suggested using private browsing mode or turning off the feature in the meantime. For a full walkthrough on how to switch off the New Tab page, see the Firefox 13 support page.
