@paintingmythoughts I agree it is weird to have tabs in the top position away from the page they are and represent, instead of the location bar and bookmarks above them.
It creates a weird disconnect between the page and the tab header... but that is common these days, tbf. -Chloe

And sys and Opera specs:
Opera One(version: 104.0.4944.28)
Opera is up to date
Update stream:Stable
System:Windows 10 64-bit
Chromium version:118.0.5993.89

So the help page says O menu > Themes to get new themes--- only there is no "themes" thing on the O Menu. And the "addons" link only has extensions.

Seriously, how TF do you get a theme on this browser?!
