I have installed the lastest Opera One(version: 105.0.4970.16).
And on its actionbar, it's got some buttons, I will never use, I think. I would prefer, if I can have some personal bookmarks there, namely 1) Bank button, 2) Google map, 3) Amazon and 4) Youtube. They are sort of required by government, also youtube because you must check their news - though it could be better channel, since one has to search in all their garbage to find relevant news like covid.
Feedback: I don't quite follow, what 'opera' is. Some jerk might explain it in comment hereafter, but it's the product that should tell it!
Yes, I can't tell either what 'firefox' or 'chrome' mean, but is this your explanation??
