I know that there won't be a problem (data corruption or whatever) when it starts up again. If there's some other problem (laptop battery down), it opens the tabs I had open if I tell it to.
That's not true actually. I've had Chrome fucked up several times after crashing or computer suddenly going down. So much that it was unable to recover and I had to manually go into the hidden applications data folder and delete all files it used. At the same time Chrome also couldn't recover the passwords file, so I had to start writing them all in again (thank god I use password manager and didn't only rely on Chrome's ability to remember the passwords).
