Settings > Internet Downloads > Advanced Settings > HTTP and click the "Reinstall FireFox HTTPS Monitor" button to reinstall certificates to FireFox.
Firefox has its own certificate store. When JMR is run for the first time in AUTO mode the CA generated during installation is installed into Firefox and you will receive a popup saying as much and to restart FF if it is running.
If you reinstall FF and its certificate store is removed then you need to add it back in via the button above or by reinstalling JMR. When JMR is upgraded or installed then a new CA is created during the installation process and the CA will be installed into firefox the next time you go into AUTO mode.
After the update I have problems with some websites that used to work just fine When Jaksta is is auto-detect mode, these websites show this kind of error: "An error occurred during a connection to www.zdf.de. Peer’s certificate has an invalid signature. Error code: SEC_ERROR_BAD_SIGNATURE". This error even shows up when I try to get to the next page on your website to post this problem! As soon as I turn off the auto-detect function, the problematic websites loadPloubalay grotte fine, but then how do I record? I run Firefox 50.0 but with Jaksta 22.214.171.124 and Firefox 50.0, this error never showed up. All my settings have stayed the same. What's going on?
Thanks for any help.
