You know what, I don't use any extra extensions, I just modify the native settings (if necessary)
Basically I do this because:
1) we do content filtering on the server side (in one of the companies where we have our own - open source mechanisms, such as heavily tuned assassin spam ii)
2) because I have had a Thunderbird for a long time (several years) so I managed to "teach him what I don't like" and he filters it 50-60% flawlessly.
3) The remaining 40% are junk messages (those that are written in accordance with the RFC (headers) and syntax in Polish and pass many spam filters - here Thunderbird helps me because a) it does not display attachments by default, but only informs that they are (and allows opening but it's the ears to open them personally)
b) if I mark an e-mail as spam once - it will be done automatically
- (I have created a rule in the configuration) it goes to the SPAM folder
each next e-mail from this account will not even remain in INBOX and will be automatically transferred to SPAM
This, combined with a rather aggressive antivirus - a lot this year's bitdefender
(and some colleagues even say that too much) pays attention to phishing attempts or malware in general
Maybe these are not very sophisticated solutions - and maybe my colleagues will suggest something else - but to me personally
to work as a security and network application engineer - so far they are enough.
for more clarity - I'm throwing a screen from my Grzmotoptak configuration (junk-email filtering issues):

UPD: One more thing - from an industry point of view - I don't do this for all accounts. I have (s) have (s) special accounts where, on the contrary, not only that we do not filter anything, but we even collect all the SPAM that comes to them and we even tried with my colleagues that they were on as many "mailing" lists as possible so that they appeared in many dangerous places. These are the accounts where we collect all potential SPAM in order to classify it later and teach our heuristic and anti-spam mechanisms. That kind of honey pot.
But, of course, we don't handle such accounts normally (read - we don't read with Thunderbird.). And at least not often and we do not click on every better attachment - unless it is a virtual machine created specifically for "accident" tests)
best regards
