In regular conditions the Restore Previous Session works as intended. But if I open a private tab and then close my regular tabs (so only private tab is left open) firefox won't restore the closed tabs the next time I open it. It never happened with other browsers that I used in the past. Is there any way to fix this by tweaking config or smth? I think this might be caused by the fact that you can reopen closed tabs in private session with ctrl + shift + t, but I don't know the setting name to test it.
