Are you sure you don't have some other software updating Firefox in the background?

Normally this only happens on Linux when your package manager updates Firefox while it's running, and on Windows that doesn't happen because Firefox updates itself only when you (re)start it.

I'm pretty sure it's impossible to keep everything arranged "correctly" geographically while keeping the proportions correct and having them be regular shapes. If anything it's impressive that you can get it as close as this.

There is an advantage to the "new" model - when you subscribe, you retroactively get access to all past content as well.

most newly created apps are using flutter

Do you have some examples? I've never heard of any desktop apps using Flutter, and trying to Google for examples only leads me to obscure ones I've never heard of.
