I've found that some of my emaIls in very latest Thunderbird mail client on Windows 10 have had their content replaced with a phishing email - the title of the email is as per the existing email received yesterday but the content is a phishing email made to look like a contact request from a motor insurance provider that I used years ago and the email is addressed to the email address I used when dealing with said insurance company. It's only an issue with Thunderbird as the email looks fine on my mobile phone and in Outlook. Either Thunderbird itself is compromised or one of the installed extensions is compromised.
Has anyone come across a similar issue?
I'm running an antivirus scan but I think I might uninstall and wipe clean Thunderbird if the scan shows no issues.
