I mean, I like Firefox, but I’d love to see Vivaldi based on Firefox/Gecko. There’s Floorp, which is similar in some ways but it’s more like an Edge built on Firefox than Vivaldi.
Edit: Thank y’all for your answers. :D
I want to link !@bdonvr@thelemmy.club 's post because it is a similar quesion. https://thelemmy.club/post/718914
It’s now been replaced by “no message, but sort of only works with Chromium”. As a full-time Firefox user I unfortunately see an increasing trend of “not working right with FF”
As a web dev and firefox user, I really wish more devs tested in Firefox by default. Almost always if it works in FF it works in Chrome, but that’s very much not the case the other way around. I’ve never run into a situation where there’s not an easy pre-existing solution to any compatibility issues, but you’ll only know there’s a problem if you actually see it.
