For as long as the funding for Firefox continues, it remains a viable option. And despite all their bad decisions of late, they still give users the ability to configure or disable user hostile components.
Their funding model is a risk, but I've been using Firefox and librewolf forever and I'd argue it's a much better option than chrome or edge, especially with a handful of plugins. A risk is still better than the actual realization of the risk.
Even if that were true, it's still a better option _today_.
