Firefox has disabled Kaspersky and Logitech, how do I re-enable them?
In Firefox Add-On it's telling me that both Kasperky Protection and Logitech Setpoint can not be verified for use in Firefox and have been disable. The info goes on about 'signing', but I cannot understand what it's telling me how how to re-enable Kaspersky and Logitech.

Override add-on signing (advanced users): You can override this setting by changing the xpinstall.signatures.required preference to false in the Firefox Configuration Editor (about:config typed in the URL bar). Support is not available for any changes made with the Configuration Editor so please do this at your own risk.
Note: That pref will be gone in Firefox 44 (Release slated for Jan 26. 2016) so user's of currently un-signed extensions should contact the developers of those extensions and prod them into getting their act together & get their extensions signed by Mozilla. Otherwise the users of those extensions will be SOL come the release of Firefox 44. Mozilla has already pushed back the version in which this new security feature was to be enabled from Firefox 40 to 44. I doubt if there will be any further reprieve.
