I know I can create .desktop files. But that is really not an option at all. I cannot constantly create .desktop files simply because I want to create a shortcut. That kills basic usability of Ubuntu for me.
I switched cold turkey from Win10 to Ubuntu a while ago and have been very happy since. Now that I start using it as my daily OS, this little issue is massively annoying… The fact it works on the PC means the only issue is the icon that is missing.
I am wondering if that missing icon has more to do with Firefox than with the OS…
