I've been using Opera for many, many years, but with each "update" it gets worse, heavier and heavier, consuming more memory and processing and less efficient. In my opinion, the development team works hard to make it worse than the previous version. previous. The "improvements" actually ruin the browser, the concern with efficiency, lightness, low consumption and usability is almost nil, for years the configuration page is one of the undeniable examples of this, because every time you access a configuration subframe as per example the sub-configuration of the sidebar and you click on return to continue configuring the other options it does not return to where you were, but to the top of the configuration page and does this in all sub-options causing the user an unnecessary waste of time and irritating.
Account synchronization in the browser is equally inefficient, as it does not recover the user's full settings, making the synchronization service a real joke, as its reason for existing "synchronize user data" is not fulfilled, as after losing an entire time configuring, creating an account to supposedly synchronize your configuration work, is ineffectively null, because right after synchronizing, what you disabled in the previous configuration is there, enabled and disrespecting your right not to use it, it is as if the developer was saying that he doesn't respect you, that what you as a user want doesn't matter to him, nor to the development team. Whether or not these statements of mine will be taken into account by the Opera team I don't know, what I do know is that there seems to be no one concerned with what the user needs and that there is no team or team that controls "Quality" of this browser, which I am no longer recommending to my clients for the same reasons above.
