It may take awhile for updates to propagate through all the versions, and repos. Since Slackware has the 'Allow Firefox to install and run studies' disabled as a big fat security whole, and runs an older ESR, Slackware Firefox may not get fixed until a new version roles in the patches repo. That said, add-on signing is really no as secure as Mozilla will have you believe (pretty much any tom, dick, harry, mary, jane or alice can apply), you can get the add-ons/extensions back via about:config search for 'xpinstall.signatures.required' right-click and toggle to "False" Your add-ons will now be re-enabled with a warning message. Have fun! Ed
