The browser remembers your preferred location for saved bookmarks, displays the bookmark toolbar by default on the new tabs, and gives easy access to the bookmarks via a toolbar folder. Mozilla’s release notes also said that Firefox 85 would make it easier to save and access bookmarks. The partitioning applies to all third-party resources embedded on a website. The latest version of Firefox partitions pooled connections, prefetch connections, preconnect connections, speculative connections, and TLS session identifiers, in order to protect users from connection-based tracking. Mozilla claims that Firefox 85 partitions all of the following caches by the top-level site being visited: Alt-Svc cache, DNS cache, favicon cache, font cache, HSTS cache, HTTP Authentication cache, HTTP cache, image cache, OCSP cache, style sheet cache, and TLS certificate cache. This means that while cached images will still load when a user revisits the same site, those caches won’t be shared by the browser across sites.
Mozilla claims that the changes made in Firefox 85 will greatly reduce the effectiveness of cache-based suppercookies and would eliminate a tracker’s ability to use them across website.įirefox 85 uses a different image cache for every website a user visits, according to Mozilla. Supercookies can be used in place of ordinary cookies to store user identifiers, but are harder to delete and block, making it difficult for users to protect their privacy while browsing. Firefox 85 stable release aims to isolate supercookies to prevent them from tracking users’ Web browsing from one site to the next. Calling it a “fundamental’ change,” Mozilla explained in a blog post that Firefox 85 would partition network connections and caches by the website being visited.
