Same here. Opened Firefox after finally getting back online after some rogue Spectrum tech showed up and no-notice, no-knock, no-call shut us off because he claimed there was some unspecified issue with our modem. ALL of my extensions, notably security add-ons I choose to use for obvious reasons, are gone. You think you can go to the web and not be hassled, especially by something like your choice of browsers. What a joke. Once I can recover how I had my firefox set up I'm seeking an alternative.
