Extension disabled could not be verified

The Extension ICBCClrCache was disabled by Firefox 50.1.0 and I cannot Enable it, although xpinstall.signatures.required is set to FALSE.

Please note that this Extension is REQUIRED by Internet Banking and that I now can no longer access my bank account, which is of course UNACCEPTABLE.

Fortunately Internet Explorer and Chrome still work, so I have to switch Browser.

xpinstall.signatures.required is an old preference that was deprecated in Firefox 45. No longer applicable.

Please contact your bank for an updated version of that Firefox extension.
