I have about 15 Firefox windows open right now. One of them probably has close to 50 tabs going on it. That one Firefox Window will no longer open for me.
I have tried shutting off my computer different ways without shutting down Firefox so hoping that when I restart the computer Firefox will give me the option of restoring past Windows and Tabs. I just planned to un-check a bunch of the Tabs in the Firefox window that had too many Tabs running.
Problem is, I cannot get that restore Window to appear. All that happens is that all the past open Firefox Windows just automatically start up without giving me the one restore Window. Is there any way around this? Thanks.

After two abnormal shut-downs, Firefox should present you with the "this is embarrassing" dialog allowing you to select which windows/tabs you want to open. You can change your preferences so that Firefox does this after any crash.
(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 filter box, type or paste session and pause while the list is filtered
(3) Double-click browser.sessionstore.max_resumed_crashes and set the value to 0 (that's a zero).
To "crash" Firefox, you can use the Windows Task Manager (Ctrl+Shift+Esc), Processes tab, to End Process for firefox.exe.
Be aware that session restore handles a limited number of windows and tabs, as you can see in about:config. I assume these values can be increased somewhat, but whether setting browser.sessionstore.max_tabs_undo to 50 will actually work I have no idea.
