Hi there. Since a few weeks firefox refuses to open websites more and more. these are websites that can be opened without problems by other browsers (like "brave"). The error i posted above IS ONLY ONE OF PLENTY SIMILAR ERRORS shown on that occasions. It seems to be always a different one. This is going on also when i make an exception in MalwareBytes, which i am using for quite some time now with unchanged settings, and never had issues like that before. Couldn´t find any help on the support pages..... This is a relatively new problem (2-3 updates) and i want to keep using Firefox

OCSP data is send along with the response headers by website to speedup transferring data (i.e. no need to check the OCSP server directly). It doesn't make sense that you experience that many OCSP issues, so it is possible that you have other (security) software messing with the HTTP response headers. An OCSP response is only valid for a short time frame and then needs to be renewed.
