First post, by Jens
Hello, i noticed that i wrote to much. So, here my edited request in (hopefully clearer) "compact mode":
- I'm experimenting with old FFes (legacy, prior v53). My favorite is 'Light', a lean FF49. Due to out-dated certs i get errors for most https-sites. Sure i can make exceptions for each, but that's unnerving and expires within 3 months.
Is there a kill-switch in about:config to override the cert-validation = make FF treat every https site like unencrypted http = accept any outdated or non-existing cert as valid by default? If not, how can i import a to-date cert8.db? Copy & paste from more recent FFs does'nt work, maybe there are other files to consider? Matching tips i found in www are obsolete and do'nt work.
Pls, i do'nt want to start a security-discussion. I'm not dumbo & aware of the risks when surfing to unverified sites, even exotic ones like https://google.com.
