I am unable (again) to access https://bugs.kde.org from Firefox 44.0.2 (F23). This was fixed last the last time but it seems to have returned. Reproducible: Always Steps to Reproduce: Try to access 'https://bugs.kde.org' from Firefox 44.0.2 Actual Results: With Firefox 44.0.2: "Un error ha ocurrido al conectarse a bugs.kde.org. La respuesta de OCSP tiene una firma no válida. (Código de error: sec_error_ocsp_bad_signature) " With Konqueror: It just works. Expected Results: No error when using Firefox. People using Firefox might think that the website is offline or misconfigured unless they try another browser.
This is due to unknown causes and only affects Firefox - further it is only temporary in nature and clears itself within a few hours. Next time this occurs, please disable OCSP validation, or use a different browser in the interim. We have no idea what causes it, and to our knowledge, our configuration is fine (the relevant section is line-for-line exact with a configuration Mozilla themselves use)
