Lowering the security level in settings.
Making changes in noscript.
This is too broad a question to answer - I also do not work on tor (little t) nor tails. I work with (not for) the apps team on Tor Browser where we mitigate state tracking, navigational tracking (if we can), and stateless tracking - as well as limit disk leaks. This is all well documented - see FPI (First Party Isolation), RFP (privacy.resistFingerprinting).
Sorry, can’t help you there. I do not work with little-t tor - I am not into networking - I work on the app, mainly in fingerprinting mitigations - 99.9% research + testing and 0.1% inspiration/success
