This applies to paypal.com and several other sites. Tried deleting cert8.db - no different. Tried Resetting Firefox - no different. Tried uninstalling Firefox and Profiles and reinstalling - no different. I have recently updated Kaspersky but my ebanking site which uses a Kaspersky licence is OK on Safari but not Firefox. Help!

Hello kenrichey, probably you have to enable ssl 3 again(in firefox 34 ssl 3 is disable by default, see why in the link at the end of my reply), go to about:config, copy the next bold security.tls.version.min and paste it in the search field, now double-click on it and change the value to 0 (zero), exit about:config page, exit firefox, and then restart firefox.

if that did not help, then go back and reverse the value again.

Thank you for the information. Changing security.tls.version.min to 0 did not help so, as advised, changed back to the default 1. However, my ebanking account now works but Paypal still blocked.
