Is there a way to prevent loading of tracking pixels on Mozilla Thunderbird ? I know there's a way to prevent loading images by default but I'd like to be able to load images without having to worry about being tracked. Basically, I'm looking for some configuration setting (or addon) that gives me the functionality of uBlock Origin on Mozilla Thunderbird.
Thunderbird on Linux, I assume Windows is similar, has 3 viewing settings:
Message Body As
- Original HTML
- Simple HTML
- Plain Text
Original will pull from remote locations to include trackers.
Simple will display only embedded content such as attachments or inline pictures.
Plain is text only with no HTML processing at all.
Setting to "Simple" will eliminate tracker loading as well as all remote loads.
Have you tried with a simple firewall rule to block everything but port 25, 465, 587, 993? I.E:
netsh advfirewall firewall add rule name="Thunderbird" dir=out action=block protocol=TCP remoteport=1-24,26-464,466-586,588-992,994-65535 profile=any program="C:\pathToFolder\Mozilla Thunderbird\thunderbird.exe"
