I think the issue is the one I mentioned above.
Tor Browser 9.5.4 (Based on Mozilla Firefox 68.12.0ESR) (32-bit)
I have a hundred years old. For months through this mixer changed, there were no problems.
After the output nodes stands VPN - as an extension in the browser - HOXX VPN, Setup VPN, Hotspot Shield VPN
Changed through the white site chipmixer.com (in my old tor browser the onion v3 is not supported, only v2)
In addition to expansion: Adblock Plus, Blockchair. Cookie Quick Manager, Free Adroid Online Emulator APKONLINE, HTTP Header Live, Https Everywhere, Metamask, Noscript, Google Translate, Webrtc Leak Shield
They stood and stand (did not add anything) months, if not years. The browser itself also does not update for certain reasons.
I do not understand who could steal ...
Oh errrr. I think there's a known problem with using clearnet services over tor since the exit node, if malicious, can serve you it's own website instead of chipmixer's which might have happened in this case. I'm not sure exactly how that works though.
You really should update tor too... But the v2 service is still accessible and probably archived in many places if you need to cross reference it.
