I left Google Chrome a week ago, and just wondering what would be some good security addons to use in Firefox? I haven’t used an antivirus besides Windows Defender for a few months now and so far no malware issues at all. Anything in Firefox addon wise that you would recommend to help protect me farther?
uBlock Origin and HTTPS Everywhere definatly.
