For the last couple of days, the address bar on the web apps that I've installed to my taskbar has been shrunk to about a third its usual length. I don't have flexible space put anywhere on my toolbar, and the problem is only on the sites I've put in the taskbar, not in regular browser windows. Is there a way to fix it, and get it back so it reaches all the way to the extension icons?

I'm using Firefox 147.0.1 on Windows 11, Version 25H2, Build 26200.7623, if that helps
