I’m obviously biased since I grew up with this “9,81” being a decimal, but in my head just thinking about it, it also makes sense. As you can see in these sentences, a comma is a break in a sentence, while a dot ends a sentence. Then again, math gets really messy when you have horizontal vectors with decimal numbers in-between, so maybe the dot is actually better idk. Eg: (2,3 , 4,5 , 3,7)

That is not what socialism is?

I honestly don’t think I found a website that doesn’t work in Firefox for years. But I agree that it can be really annoying, I hope more people adopt Firefox (or it’s engine at least).

As for your iPhone issue: Well Apple doesn’t really allow any other browsers on iOS, AFAIK it’s all just Safari under the hood with a skin on top.
