My one, sole issue with LibreWolf is—and correct me if I’m wrong—it still relies heavily upon Mozilla’s efforts in developing Firefox. LibreWolf is not a standalone fork, just a downstream improvement.

It really sucks, because apparently, developing a web browser is hard. Until we can manage to get a browser that’s completely free from Chromium and Firefox, we’re kinda stuck with the Mozilla hand that feeds us as the current best option.
