Yes, that is normal. You want to turn that off? There are a couple of settings related to resuming your previous session after a crash: (A) Resume automatically, but if Firefox crashes twice in a row, show a list of windows and tabs and let me choose; (default)<br> (B) Don't resume automatically, always show a list of windows and tabs and let me choose; (I recommend this approach) or <br> (C) Never resume automatically, and don't show the list. Switching to B or C requires a visit to Firefox's about:config preferences editor. (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful. (2) In the search box above the list, type or paste '''sess''' and pause while the list is filtered For "B": Double-click the '''browser.sessionstore.max_resumed_crashes''' preference and change from 1 to 0 (that's a zero). For "C": Double-click the '''browser.sessionstore.resume_from_crash''' preference to switch its value from true to false.
