The graphical user interface of Windows 7 is similar to Windows Vista, glass-like interface design (known as Windows Aero) is available in all versions of Windows 7 (except the Starter Edition). Windows 7 (the successor to Windows Vista) was released to the public on October 22, 2009, and was more successful than Windows Vista. General information from Windows 7 (for all editions) N, KN versions, and VL build ISO files are available in the download menu. The 32-bit version of Windows 7 Professional version supports up to 4 GB RAM, while the 64-bit version supports 192 GB RAM, as well as supports up to two physical processors in the system. Compared to Windows 7 Home Premium, Professional Edition has more RAM and CPU support. If you need to run 32-bit Firefox or manually install 64-bit Firefox, you can simply download and re-run the Windows (32-bit or 64-bit) Firefox installer from the Firefox platforms and languages download page.Windows 7 Professional edition was designed for small business and professional users, it has all the features of Home Basic and Home Premium editions, and it includes addition features like Encrypting File System, Logical Disk Manager, Offline files, Windows Server Domain join, Windows XP Mode, and more.

You can still manually install 64-bit Firefox, if you choose. If you see “(32-bit)” and are running Firefox 56.0.1 or newer, then your computer may not meet the minimum memory requirement for 64-bit (3 GB RAM or more).If you see “(32-bit)” and you are running Firefox 56.0 or older, updating to the latest Firefox version should automatically upgrade you to 64-bit.Check your Firefox version (in the “About Firefox” window) and look for “(32-bit)” or “(64-bit)” after the version number: If you’re running 64-bit Windows ( here’s how to check), your Firefox may already be 64-bit. Linux and macOS users, fret not, you already enjoy a Firefox that’s optimized for 64-bit. Also, with the jump from 32 to 64 bits, a security feature called Address Space Layout Randomization (ASLR) works better to protect you from attackers. Here’s the key thing to know: 64-bit applications can access more memory and are less likely to crash than 32-bit applications. What’s the difference between 32-bit and 64-bit? How much less? In our tests so far, 64-bit Firefox reduced crashes by 39% on machines with 4GB of RAM or more.

That means you get a more secure version of Firefox, one that also crashes a whole lot less. Users on 64-bit Windows who download Firefox can get our 64-bit version by default.
