Project mention: Ask HN: Which web browser are you using and why? | news.ycombinator.com | 2025-12-03
Most chromium-based browsers feel the same and its disappointing. If I wasn't as happy with the gnome skin for firefox I'd probably be using Zen [1] because its nice to see a firefox based browser that tries to introduce new features and create an identity of its own instead of joining a size measuring contest on how hard(ened) they are (I respect them, but it's a very saturated market at this point).
