console still has remnants of previous user commands
I do not know when/if this was a thing that was patched, but it seems so, since the behavior is different to FF
On stable 12 I have nothing. But as an example on my stable, I restart, open the console (ctrl-k) and arrow up and there is nothing. Now I type navigator.appCodeName
and hit enter. Close the browser, restart, open console and arrow up and nothing is retained
On my alpha however, I do have entries. If I add a new one and restart, the new one is not remembered, but the original remnants are there. Where are they? Can we add some code to clear it out properly? But only if this was a thing TB patched.
PS: I don't do much testing in TB stable TBH
