Pale Moon - Your browser, Your way

Download Pale Moon x64 - 25.3.1

If you run a 64-bit operating system, you can choose to download and install a native 64-bit version of Pale Moon, a so-called "x64 build".
Without having to use the 32-bit compatibility layer in 64-bit Windows, native 64-bit browsers in general run faster and more efficient than their 32-bit counterparts, although synthetic tests will not provide you with conclusive results. Most notably, you may see lower CPU strain running Pale Moon x64 on complex/processor-intensive web sites or sites with large amounts of data like media sites, and it will be especially beneficial if you regularly open a very large number of websites concurrently (since a 64-bit version can address all your PC's memory).

Unfortunately, there are also some drawbacks, mainly in the areas of compatibility with third-party 32-bit components to extend browser functionality. Most media-plugins are not available in an x64 version, for example.

Therefore, there are some very important things to note before you decide if you want to use an x64 build:
  1. You will need an x64 Windows Operating System! Just having a 64-bit processor is not enough, you will also have to have a 64-bit version of Windows (i.e. Windows Vista 64-bit, Windows 7 64-bit or Windows 8 64-bit).
  2. Many plugins are either not available or not officially released yet for 64-bit browsers. This will mostly hamper things like in-browser document viewers and media/gaming plugins or authentication plugins (e.g. for banking sites). Most extensions (add-ons), however, do work, not to be confused with plugins.
  3. Adobe Flash, used on many pages, is only available on the 64-bit browser if you run Windows 7 or later! Their plugin does not support Windows Vista 64-bit.
  4. Pale Moon x64 will be one of the very few, if not the only, application on your system that will use natively 64-bit hardware acceleration. Especially with embedded graphics, legacy graphics cards, hybrid systems with 2 GPUs, or new operating systems, this may cause (sometimes severe) problems that would otherwise not show up. Native 64-bit graphical hardware acceleration is still in need of development by a large number of driver manufacturers, and you may run into unexpected problems like memory inflation (excessive memory use by the browser), hangs or lockups of your graphics card or operating system due to driver bugs. You may have to switch to the 32-bit build of Pale Moon if you run into issues because of this; a solution is not always available.
If you understand what you are getting yourself into, then by all means, grab yourself a copy of Pale Moon x64, and enjoy!
