What's your opinion on Opera browser? - eviltoast

I’ve been using Opera for a few years now, ever since my brother recommended it to me, and I’ve been enjoying its features, UI and everything. However, I (surprisingly to me) haven’t noticed many people mentioning it. Also, when I was on Reddit and mentioned that I use it I got downvoted which left me somewhat confused haha.

So I’m wondering if there’s anything wrong with it and/or if I should give another browser a go (I noticed Firefox is mentioned a ton on here)
