Tor Browser seems to remember tabs *at the very moment* of a new available version

Hi,

Sorry if this is a duplicate, I tried to give a look but didn't find anything. And sorry for the weird title, couldn't find anything better...

I'm not sure exactly what happened, but here is, in order, what I did/saw:

• open tor browser (under debian stretch)
• open a few tabs
• "new identity"
• open some tabs
• "new identity"
• open some tabs
• close tor browser
• see a "new version available" window
• click on something like "yeay, let's upgrade" (maybe the upgrade was done and only a "restart" was expected)
• see tor browser starting and opening the tabs I had open some time ago (not the last "identity", but the first one)

Voilà. I probably could give more details if needed.

Oh, also, I cannot say when that "Upgrade available" window appeared, I only saw it when I closed Tor Browser.

I think it's a privacy issue (the tabs are stored somewhere or whatever).

Thanks
