So, what’s new in this release? Mozilla have changed the default homepage layout a bit and now, opening a new tab gives you quicker access to all you bookmarks, history, settings and a lot more. Another neat feature that’s borrowed from Chrome, is opening a new tab will also show you your most visited pages so one can jump directly to it rather than having to type out the URL. A couple of changes include the SPDY protocol, which is now enabled by default allowing faster browsing on supported sites. Opening a browser for the first time will not restore background tabs by default. This change was made in for a faster startup time. Smooth scrolling is also now activated from the get go. Mozilla have also added some new features for developers. There are a total of 72 improvements to Page Inspector, HTML panel, Style Inspector, Scratchpad and Style Editor. The new column-fill CSS property has also been implemented. Mozilla have added experimental support for ECMAScript 6 Map and Set objects have been implemented. Since this is still in Beta, there are some known issues as well that you need to be aware off. For instance, if you try to start Firefox using a locked profile, it will crash. Some users have experienced slower scrolling on the main Gmail page. Certain Synaptic touchpads are unable to scroll.
Go ahead and give it a try and let us know what you think.
