As far as I know, OCSP checking is enabled by default in Firefox and the default timeout is 2000ms.
I am interested to know whether the request is blocking call, ie: the page load halts before the OCSP response(s) are at hand.
Furthermore, which files should I edit to 1) disable OCSP checking, 2) Increase the timeout value of OCSP checking.
P.S. I am building Firefox on Linux using this manual: https://firefox-source-docs.mozilla.org/setup/linux_build.html
