The tabs are still there even if you miss the prompt. Either press Ctrl-Shift-T, or select the three dots => History and the tabs are there, under the "Recently closed" section. The caveat is that you have to restore the tabs before you've browsed enough pages that the tabs are pushed out of the recently closed tabs. Also, I simulate Chrome crashing by sending SIGSEGV signal to it, but I'm pretty sure this applies even if Chrome crashes for real.

Well we are seeing major browsers limit control in recent updates, so that's the new major browser race it seems. Safari and Chrome are locking down what you can do with extensions, which limits what you can do to protect your privacy online.

web standards are always evolving and updating. A lot of users don't appreciate that it's happening but it is. Firefox and Chrome do a pretty good job of keeping up. Chrome also adds a lot of proprietary additions to push the envelope as well as differentiate Chrome as well.
