If you make a fresh Ubuntu user and log in as that, does the browser work OK there?

yes, it seems to be OK.

 I have several add ons (disconnect, decentraleyes, cookie autodelete, ublock origin, bitwarden, https everywhere, privacy badger, video downloader and consent-o-matic) that I'm going to remove and replace one by one until see any problem.

And I going to assign for my firefox account (it logout automatically).

Any case many thanks for the help.

OK then you know its settings and not the application by testing with the new account as you got vanilla settings
