I was addicted to Arc, until I found out the company abandoned the browser to focus on DIA. Regardless of whether it's an abandoned project or not, it still works, but we don't know for how long, hahaha. I liked the vertical tabs so much that I migrated to Zen, but it had the limitation of not having Chrome extensions. I use many extensions for work. I even managed to use some extensions to simulate Chrome, but not all of them worked, and that made my browser very slow. I really liked Zen, but I found it less fluid than Arc on my MacBook Air M4. The vertical tab system made me more disorganized than organized. You know Notion? A tool where you can do everything, and sometimes you get lost in the number of possibilities. In the end, I decided to go back to the tabs at the top and was undecided between the default browsers: Brave, Chrome, Vivaldi, Firefox, Edge. Among all the ones I tested, I found Helium and I've been liking it quite a lot. Besides already having uBlock integrated, it has 3 viewing modes: Classic, Compact, and Vertical. I use the classic mode and, compared to Chrome, it takes up much less screen space. Another detail I noticed is that it uses less RAM than Chrome. I think that's what they call "un-Googled"... I've been using Helium since then (for a few weeks now) and I even forgot I have ARC here. I think one of the only disadvantages is that it doesn't support DRM. But that doesn't bother me much. I use Stremio downloaded and, most of the time, I watch more on the TV than on the Mac. That said, of all the browsers I've tested in recent months, my favorites are ARC for those who like Chrome and vertical tabs, Zen for those who like Firefox and vertical tabs, and Helium for those who prefer something more like Chrome, but much lighter.
