Thunderbird corrupted networking over hidden services

Thunderbird somehow after torbirdy removed because of its outdated and not compatible with the current Thunderbird version, trying to link your email smtp/pop over tor hidden services just doesnt work. I tried this with riseup and danwin1210 email providers both doesnt work, Testing it using plain debian + tor + proxychains + thunderbird it will work fine.

I opened ticket with riseup they confirmed to me that all their servers working and they are using onion hidden services.

So the issue within whonix firewall or so.

if you’re using qubes, that may be the difference. This is with kvm on a debian host. there’s nothing particularly modified about it. whonix firewall is at deafults. thunderbird connection ip/port =

got new report for the same issue on IRC, this is whonix-qubes issue.

The problem is occurred due to default network setting from Thunderbird.
Follow it below. I’ve got this settings from Tails OS.

Edit (from Thunderbird Menu Bar) -> Preferences -> Advanced -> Network & Disk Space -> Connection -> Settings…
-> Select ‘Manual proxy configuration:’
-> Type SOCKS HOST: ‘’ Port: ‘9050’
-> Check ‘SOCKS v5’
-> Check ‘Proxy DNS when using SOCKS v5’

I’ve tested Whonix VirtualBox
