Here’s the key thing to know: 64-bit applications can access more memory and are less likely to crash than 32-bit applications. Also, with the jump from 32 to 64 bits, a security feature called <a href="{ $ASLR }">Address Space Layout Randomization (ASLR)</a> works better to protect you from attackers. { -brand-name-linux } and { -brand-name-mac } users, fret not, you already enjoy a { -brand-name-firefox } that’s optimized for 64-bit.
更关键的是：64 位应用程序可以访问更多的内存，且比 32 位应用程序崩溃率更低。此外，随着从 32 位过渡至 64 位，名为<a href="{ $ASLR }">地址空间布局随机化（ASLR）</a>的安全功能可以更好地保护您免受攻击。{ -brand-name-linux } 和 { -brand-name-mac } 用户不必担心，您已经在使用为 64 位优化过的 { -brand-name-firefox }。
