I accidentally selected “Close other tabs”; I then immediately pressed Ctrl+Shift+T several times until no more tabs would reopen. I can’t remember how many tabs I had before; I know I had alot. Were all of them reopened, or did I lose some?
This is a nifty trick, CTRL+SHIFT+T. I use it all the time, btw for those just learning, I don’t think it works when incognito in some browsers.
To answer your question, it depends on how many you had opened that you can keep track of. If you really want to know how many tabs there we’re I’d suggest looking through your history and re-opening them all up again.
