Hello @boson96 thank you for reaching us out. That toolbar appears because of you have group of tabs, if you drag a tab upon another one this toolbar at the bottom will show up however you can disable by going to:
Settings → Appearance and turn off Enable Tab Group auto creation so will see the normal view of tabs, now regarding the top bar would be better to check on twitter if you have allowed a setting or option to enable that and disable it from there.
