Yup. So many of these "alternative" browsers have very questionable security practices. At the very minimum they don't have a staffed team to respond to zero-day exploits. But often they also make large changes without too much consideration for security or disable security features when they get in the way of features. I hate saying "use on of the big boys" but for most users their browser is likely their largest attack surface by an order of magnitude, it's job is literally to download an execute untrusted code and the API surface is huge. It takes real resources and careful development to develop and maintain a browser, and there are very few organizations that I would trust to do this.
So unless you have a strong reason I would highly recommend sticking to one of the major browsers.
