I am tempted to start using the @Vivaldi browser but then I looked* at the diversity in the underlying technology and I think it is better to promote and start using @firefox 
more.
Or should we leave it to #Google 
and #Apple 
only❓
I'm curious 😅 @Vivaldi why not use SpiderMonkey and Gecko❓

1. There is no adequate addition of your search engines
2. Keyboard shortcuts cannot be changed
3. You cannot copy links of multiple selected tabs
4. Bad inspector. It is much better in Chromium browsers.
5. No task manager. More precisely, firefox has something similar, but when you want to free the memory of the tab, firefox closes it, and I don't need is

And I still want something that is not in any browser, so I did not add them to this list (and it is also difficult to formulate them because I only remember them when they can be useful)
Basically, Opera and Vivaldi are suitable for points 2-5 (and even for the first point, Vivaldi is suitable, but partially). But they are all closed source and therefore not suitable. So I have to work on Firefox
2/?
P.S. Chrome/Chromium/Ungoogled Chromium - do not offer because they have a terrible inconvenient interface and 0 possibilities to configure something.
The only option that suits me is probably to make my browser based on either Firefox or Ungoogled Chromium. But I don't know how, even though I'm a programmer
