Bug 1735748 will disable F5/Cmd+R in the browser toolbox, which was doing only a light reload, reloading only the current toplevel browser.xhtml document.
But this will enable Cmd+Alt+R, which do a full restart (process restart). There is still cases where the browser toolbox won't restart if you restart too quickly and session store didn't have time to save data to disk.
This is based on this key shortcut:

I tried to investigate a bit the SessionStore codebase but wasn't able to find any API to force writing SessionStore to disk before restart.
Jared, if you have any suggestion on how to do that, that would be super helpful!

If you could dispatch an event when the Browser Toolbox opens, SessionStore could listen for it and trigger a delayed save. It wouldn't be guaranteed but would probably work for most cases, https://searchfox.org/mozilla-central/rev/15b656909e77d3048d4652b894f79a8c719b4b86/browser/components/sessionstore/SessionStore.jsm#1516-1519

Oh but wait, the session store codepath we are using is only trigerred when the user manually ask to restore its previous tabs:
https://searchfox.org/mozilla-central/rev/3aaca0a12a2d1463da54933bdbdae2f06fead06f/browser/components/sessionstore/SessionStore.jsm#3834
https://searchfox.org/mozilla-central/rev/3aaca0a12a2d1463da54933bdbdae2f06fead06f/browser/base/content/browser-menubar.inc#248
So that, if you weren't having any tab, you wouldn't even see the menu entry to restore tabs (nor devtools).
We should probably find some other ways to save and restore devtools state, which wouldn't be tied to tabs.

I'm now wondering which API we could be using. There must be some other component to save such state across reloads.
Or should we be using preferences? custom IndexedDB? custom file in profile?

The answer to your question is, I think, XULStore.
