Firefox is still there. There is more than Chromium based browsers. Safari uses its own engine. Gnome, KDE have their own browsers with their own engines, there are text browsers, experimental browsers, etc. There could be a completely new browser next week that works with 99.9999% of web pages, thanks to web standards. But even a Chromium based browser setting is better than some random app that could have been a web page.
