Mozilla introduced the ESR channel specifically for organizations like universities, governments, and enterprises that cannot keep up with the rapid six-week release cycle of standard Firefox. While the standard browser moves quickly, adding features and potentially breaking legacy intranet applications, the ESR version remains static for approximately one year, receiving only high-risk security patches. This ensures stability for critical infrastructure.

While 64-bit computing had been standard for years by 2017, many older machines—particularly those running Windows XP (which Firefox supported until version 52) or older versions of Windows 7—required 32-bit software. Furthermore, some legacy applications were coded specifically to interact with 32-bit browser components. Hence, the 32-bit version of Firefox 52 ESR became a specific necessity for millions of older workstations worldwide.
