Unfortunately, as of today, there are really only two core browsers left which support the modern web.
Your choices are either Chromium (the upstream for Google Chrome), and one of it’s dozens of derivatives, or Mozilla Firefox, and one of it’s, entirely forgettable, and likely, even more buggy, offshoots.
The browser industry is currently caught in a death spiral of such rapid competition, and fast-paced development, in an attempt to keep up with the quickly evolving standards of the web, that neither gets the needed time to properly optimize in the way they should. While there have been strides in browser efficiency, such things often take a back seat, in the face of ensuring that they support the latest protocols, standards, and security. The result being that, every year, both browsers become a little slower, harder to maintain, and much harder to compete with, as, taking the time to properly optimize every feature, would take weeks of development time that nether team can afford in such a fast-paced landscape, and anyone trying to start from scratch has miles to run to play catch-up with the two biggest competitors.
To say that the current state of the web is, “bleak”, would be, entirely justified, and, an understatement.
While there are projects attempting to build browsers that are more efficient, most lack the funding, the development force, and the support needed to keep up with the modern web. Many are left in a state of poor maintenance, where, while looking something up on Google may be perfectly fine, some sites may fail, or flat out refuse to load, with some causing outright crashes.
Essentially, in the end, until we get a new, real competitor in the browser space, there really aren’t any meaningful choices. They’re all the same internal engines, running the same, unfortunate, bloated, code. Neither side is winning this fight, and we all get to pay for it in system resources.
Apologies for the rant there, but this is a rather frustrating subject.
I’d love to say that I use Firefox because it’s objectively better, but the truth is, I’ve only stuck with it because everything else is, pretty much, equally as bad.
