Firefox is now blocking paypal. I'm unable to get to the paypal login screen because of the error: SSL_ERROR_NO_CYPHER_OVERLAP

It does the same thing with AMC Theaters when I try to checkout. Is there somewhere in firefox where I can fix this? I have to use a different browser to login to these sites.

Chosen solution

please enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for bold preferences starting with security. - right-click and reset those entries to their default values.

hello, what security software are you using (if any)?

please also go to the firefox menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum? this might give us a clue what is going on...

I'm on a mac and I'm not currently using security software.

Thank you, that worked. Not sure how they were set to user set but are now back to default.
