I am using Kubuntu 25.04. I tried support but the support in Firefox doesn't seem to have much help for OSes beyond Windows even though they make a native Linux version. I subscribe to several extensions and use Firefox sync to get the extensions onto a new computer but they don't automatically pin to the menu bar. I figured out how to do that once but I forgot how I did that and can't find it in help. Can someone please tell me how to do that. Mozilla, if you are reading this you might want to improve the support in your Linux version.
