I've visited the websites of all of the browsers you listed. All of them have the same-ish UI. I don't really know what a 'workspace browser' is so I don't have nearly as concrete of an opinion as someone that uses one of these daily. But, from the UI alone, they feel like the Opera web browser (they are definitely not the same, and probably serve different purposes but this is the impression I get). Does one of these browsers have more features? Which one do you feel comfortable using?

Also, unrelated, but can you or someone else explain to me what is a 'workspace browser'? What purpose does one of these serve?

Is there any reason these browsers would be more functional than regular Firefox with Sideberry or the Tree Style Tabs extensions?

I use Sideberry at work and at home. Between the containers, folder sorting, tab sleeping, and snapshots, I haven't found another browser configuration that's as flexible and functional.

Not to mention it works with any release or flavor of Firefox. So I don't have to worry about weird issues with non-standard browsers.

*Bonus points if you take the 10 minutes to setup a stylesheet to hide the default horizontal tabs.

I’m using Arc browser full time for work and personal use now. Absolutely in love. They’ve just released publicly after a while in closed beta, so no more invite keys needed!

I love its clean interface and focus on privacy. The extensions library isn't as vast as some, but its curated approach ensures stability and performance.

I’m using Vivaldi.

I don’t know about the ones you posted but a chromium based one is important for my workflow.

Vivaldi had some issues of crashes but I feel like with some tweaked and each update it becomes better and better.

It’s now the staple in my daily workflow now (I’m a full stack web dev)

— finally got in my preferred instance. Did not see my previous comment. Weird

I used Ferdi then Ferdium on Mac. No complaints, Ferdium actually works better than Ferdi has. No need to reload a ‘tab’ because of crashed page and it doesn’t forget the Teams account / tenant setups. It’s stable and all notifications work fine.
