Firefox is great, and the community "zen" fork is even nicer.

Been a happy user of Zen for at least a year now. Big fan of the clean UI and vertical tabs. Super stable, no issues. Not in love with their tab group implementation, but its fine.

I've wanted to love Zen for a while, I really have, but every time I start using it, it just feels... I don't know... foreign? Too new for comfort?

I think it's one of those "once you get used to it, you never go back" technologies, but I also think it takes a bit of time to get used to it. Thoughts?

Maybe you could expand inline in your comment about what makes Zen “even nicer”

Not the OP, but I appreciated its attempts to declutter and rethink the layout. It encourages a full screen, minimalist style, and jumping between workspaces for different task sets. Hovering and slide out menus rather than permanent bars (although those are still an option). It also brought in some features like Split View before they hit mainline Firefox releases.

Unfortunately, I found it had some unfortunate video playback bugs for me on Linux, so I ended up bouncing back to Firefox. I'm also bit leery of relying on smaller projects with all the supply chain issues these days...
