''Aussiemim [[#question-1284075|said]]'' <blockquote> Junk mail always went into the junk mail folder but after the last Firefox update, it is showing up in my inbox - how can I stop this? </blockquote> Hello Aussiemim, Firefox is a browser and doesn't "do" email - that this started to happen after the latest Firefox update, could be a coincidence. You could contact your email provider - see : https://support.mozilla.org/en-US/kb/problems-with-email-how-to-find-help In case you are using Thunderbird; I found this article : https://support.mozilla.org/en-US/kb/thunderbird-and-junk-spam-messages

Thank you for answering so quickly, I will try your suggestion.
