First, it is likely that Firefox 52 ESR is slower because of external factors (antivirus, security software, malware, etc) or addons.
We are extremely careful when modify Firefox ESR: we will only fix high and critical security issues, very important regressions due to new versions of operating systems or very important crashes. We have data which shows that, improving performances in a stable product, leads in 50% of the case to regressions (stability, feature, etc). Therefor, because we commit to stability to our users, we won't take any performance improvements into ESR. ESR60 will be released May 8th. Even if we recommend you wait until ESR60.1 or .2, this version will benefit from all the Quantum improvements.
