Web Browsers Stack
The most important tool to access the internet is a web browser. Nothing comes close to the power, simplicity and utility of one. It's infinitely powerful, malleable and capable; yet intuitive and simple. For most people, a device just running a browser would more then suffice.
It needs to be stable and power efficient under 3 digit tabs, allow tab view customization, avoid bloat and for the love of god - no onslaught of defective AI “features.”
As is my philosophy for most things, I use many browsers for different purposes, on different devices.
Vivaldi
Platforms: MacOS, Android and iOS. Use Case: Work & Research.

Vivaldi is the most customizable chromium based browser on desktop. I use it every single day, where, I hold far too many tabs and windows open, for research, writing, design inspiration, code lookup, uploads and website testing. It handles everything perfectly well and performance is excellent. I love making my own themes and the vertical tabs - I only wish I can hide them.
On Android Vivaldi makes mobile browsing phenomenal. It has incredible
Firefox
Platforms: MacOS, Linux occasionally iOS & Android. Use Case: Media.
This is where I stream my video on MacOS. My main Linux browser, currently on 2 PC’s. I love the extension ecosystem the most. Plus I support the mission. It's important to have an open source browser that isn't controlled by a monopolistic company. While the Firefox org has a lot of troubles and dumb decisions, I like the browser and I prefer it to Chrome.
Safari
Platforms: iOS, MacOS. Use Case: Reading, Testing.
Any browser you use on iOS is just a skin over Safari. Unsurprisingly, apple makes one of the best ones. I dislike how every tab has to open on screen, even ones open in another tab. An annoyance big enough to make me switch browsers. But I switched it to be my default browser (away from Firefox) and I use my phone a lot less. So do with that what you will.
Extras
Zen and Arc
Platforms: desktop & IOS. Use Case: Work, Media, Research
I love Arc with a passion. It’s what I’ve always wanted from a browser and I’m equally glad the open source community is taking notice. I’ve recently switched to Zen, which is based on Firefox. It’s not as good, but getting close. I am contemplating going back to Arc. I use it on IOS since it’s the easiest thing to open and search. I dislike the AI features on there, but they nailed the basics in a beautiful package.
Also, I keep Chromium around for testing. I really don’t have much to say about it.
