This error started cropping up lately, more and more: SSL_ERROR_NO_CYPHER_OVERLAP Since a couple of weeks ago I can't use one of my bank services with FF (even safe mode, no addons), but Chrome doesn't complain.

Main complaint is: this error isn't mentioned in the "Learn more…" link offered on the error page. Secondary (by not much) is: it isn't mentioned anywhere else either.

I really have searched, time and again (as in "lately" above, couple of months) hoping perhaps someone would post something helpful. Perhaps then this could be it.

Anybody out there? Any help?

HI, what Security Program are you running please ?

Please update your Video Card Drivers they are full of errors with stuff not working or are disabled. Some of that maybe because you were in Safe Mode when you supplied the information. I gather no changes for you in Safe Mode then....

adapterDescription: AMD Radeon HD 6800 Series driverDate: 4-19-2011 I would suggest running the Crimson Drivers and Download the both for storage as no more updates. These drivers are from 2015 & 16

Can you check your Device Manager for the name of your Network Card and version please. Look around for a new set of drivers. As the old drivers for video card are from 2011 I would guess that the same holds for the Network card. It may not be able to handle the TLS in it's current state.
