It becomes better after it became worse. It's not that hard to make it better after you burned all the bridges who lifted your product into the sky. Though, at this point, there isn't much left anymore outside the core-abilities.
Firefox has been always the best browser as it is the only open and free (as free from adversarial incentives).
Unfortunately many people (especially here) have advertised Chrome instead, naively believing Chrome to have these important properties.
Chrome has always been the controlled frontend for Google business and Google is readily willing to hurt the browser to aid its business and keep its dominance.
Blink is also open and free enough. The wide usage of it, and the manifold companies pushing successfully against Google, is proof enough. Firefox on the other side is not free from hostile behavior itself. The manifold bullshit that Mozilla did over the years telling.
And in general, your requirement is not matching the demand of the majority of users. I don't give a f** if something is open or liberated, I'm a user, I care firstly whether it's doing what I need, and being open&free are just tools to balance the powerplay of the creators.
But if not enough people are using the browser, they have no power anyway. And if there is only one developer, then we as the users have not way to balance our power against them. Mozilla has shown over the last decade that the user has no power in their game, which shows that free and open software in itself has little meaning.
The multiple blink-browsers are showing better how this is supposed to work, then the one project who always claims this as one of their main goals.
Majority of the Blink browser users are Chrome users, followed by Edge users and then somewhere come Opera users, what depending on the polls is on par with Firefox users or far behind it.
But none of this matters as I was talking about browsers, not browser engines, that are not the same thing and none of the Blink browsers listed above are open source browsers.
Majority of the users are using the browser they are told to use. If everyone is telling them to use Chrome, they use it. And there practically has not been much resistance to Chrome. How many IT people have told over the years to not user Chrome, and use Firefox instead? There was huge resistance to IE, but not to Chrome, and it pays now its dividends.
Is Chrome now doing what the users want? How many people are upset about the latest moves by Google. For me it was obvious result for long time, I was actually surprised that it didn't happen earlier. Now based on the reactions, many users didn't expect it.
