I have attempted to download Firefox ESR 31but although the link labels says ESR 31 it downloads ESR 38

is there a way to search with Mozilla's web site for older versions?

Thank you in advance.

Mozilla does not make older versions as something you can just download on mozilla.org as easily as current versions due to potential vulnerabilities.

Only 41.0.1 and 38.3.0 esr are supported.

Since you have Windows and want to use a old 31 ESR version for one thing there is the portable Firefox option. This will not touch your Firefox install and Profile settings. Firefox 31.8.0 esr was last however portable apps only did up to 31.7.0 for the 31 esr.

(copy and paste whole part for link into Location (address) bar

The English options are near bottom of list.

Try <removed random unofficial download site> Keep in mind that version is no longer supported. Quote from Wikipedia "End-of-life 31.x.x ESR product line on August 11, 2015".

Pappy1972, that site does not even have the Fx 31. ESR builds and there is no need to download from there when all Firefox Releases are available from mozilla.org like say http://ftp.mozilla.org if you must download a older version.
