The 64-bit builds often test slower on many browser speed tests as a result. The 64-bit builds of Firefox are not as stable or consistent as the 32-bit builds. It's important to note that this build will not work on 32-bit Windows machines and you'll have no way of knowing if it will work without checking the machine's details or just trying it. So why a 64-bit build of Firefox Nightly? It's primarily to help with testing the 64-bit builds with a wider audience to better enable bug finding and fixing.

Why 64-bit?Īs per our long-standing policy on 64-bit apps laid out in 64-bit Software: Where It Fits Into Portable Apps, we do not make available 64-bit only apps, we only do user-friendly dual-mode 32-bit//64-bit apps so they always work. Multiprocess In Nightly - You can turn on multiprocess mode in the nightly build by setting to true in about:config and then restarting Firefox. Plus, thanks to the launcher bundled in the Mozilla Firefox, Portable Edition, it leaves no personal information behind on the machine you run it on, so you can take your favorite browser along with all your favorite bookmarks and extensions with you wherever you go. It has lots of great features including popup-blocking, tabbed-browsing, integrated search, improved privacy features, automatic updating and more. Mozilla Firefox is a fast, full-featured web browser that's easy to use.
