You really don’t need anything besides uBlock Origin. With that said:

• Your password manager’s extension would be convenient.
• LibRedirect is great so that any social links get redirected to privacy-respecting frontends.
• Dark Reader to save your eyes.

About some other ones that are mentioned:

• ClearURLs is not necessary if you configure uBlock Origin to remove the tracking parameters.
• Bypass Paywalls Clean is not necessary if you configure uBlock Origin to replicate this functionality.

Other:

• Firefox Multi-Account Contains is good for managing accounts.
• Temporary Containers is also good for isolating tabs.

IIRC, Privacy Badger and Decentraleyes are no longer necessary with uBlock Origin. Neither is HTTPS Everywhere.
