I'm running Firefox 85 on Mac OS Catalina. When I open dev tools on the Network tab, the default view of the "details" panel is not very useful: it's stuck at the 40px height at the bottom. So I drag it to be half screen height in order to be able to see the panel contents. The problem is, when I restart the browser and open the dev tools again at the Network tab, my changes haven't been preserved, and the "details" panel is again at the useless 40px height. How can I make Firefox to remember the layout of panels in the dev tools?
