It's problematic, indeed.
But why do most Linux distributions (including Solus) have chosen Firefox for their installation kit?
Quite simply, because this web browser, which is supposed to respect the privacy of its users, is maintained by a foundation, Mozilla, which is a legal entity. This gives for this application a certain durability.
Of course, fork applications such as Librewolf, Mullvad, Floorp (the list is not exhaustive) have brought improvements, notably in terms of confidentiality. But they are maintained by passionate developers, sensitive to the open source philosophy. But what about their medium- or even long-term future?
The debate remains open...
