Using the new DPI SSL/TSL, Linkedin does not open with Firefox on Mac

What exa t error did FF throw? I personally got for various sites a rx reissued serial or similar error. Resetting (cleanung up) FF did resolve the issue. Seems that FF stores some cert serials, and blocks sites if a already issued serial get reused.

Maybe it helps (instead a TLS exclusion) to MITM Linkedin. In my Case Linkedin works fine intercepted.

SaschaParis, 

thanks for your input. I already cleared the cache and I obtained very little improvements, but...amazon.it works but changing from 120 to 480 GB does not work at on this link.

Clearing cache doesn't help, as FF stores cert serials.

Sascha,

it improved but the issue persists.

To reset FF on MAC, the steps are little different. https://malwaretips.com/blogs/reset-firefox-settings/

It took time to reset FF and now some sites are opening (very slowly compared to Proxy mode, but My ebay does not open at all).

Check the screenshot.
