As mentioned using a VPN is an alternative although for added privacy
using tor through a VPN gives extra privacy.
Firefox has good privacy features and I currently use this through PROTONVPN
VPN only hide your IP, it's still possible to track you through your browser's fingerprint.
If you are going to be using Tor, then it might be worthwhile bookmarking your captcha bypass login link that you can access here (
https://bitcointalk.org/captcha_code.php), as otherwise you'll be filling in captchas for 10 minutes every time you want to log in.
This is a little misinformation too. Sometimes I can log in with Tor browser within several seconds, with my first attempt. In contrast, sometimes I have to spend around several minutes (maybe longer than 10 minutes, up to 30 minutes - in such cases I get mad with failed attempts) after so many failed attempts - that what you mentioned correctly.
If it took a while, you better choose 'New Identity' or 'New Tor Circuit for this site'
