let users choose whether they need to use a new or older version of firefox it reduces search time on many systems for instance i use an i7 intel windows 10 64-bit computer and i could do better with version firefox 62.0 etc

Most software companies consider it a matter of social responsibility to only support software that has been patched against known vulnerabilities, and considering Mozilla's resources, it probably is not practical to maintain too many versions.

If the rapid release version isn't for you, check out the extended support release -- geared toward enterprise users but available to all. https://support.mozilla.org/kb/switch-to-firefox-extended-support-release-esr
