Though I updated my preferences, Firefox 4.0.1 doesn't warn me about closing tabs before I quit, and closes all tabs after I quit.
I updated to Firefox 4 yesterday. I updated my preferences, including checking the box that commands Firefox to "warn me when closing multiple tabs." Despite this, Firefox does not warn me and closes all tabs at quit. In short, I lose all my tabs whenever I quit Firefox. Please advise.

Firefox 4 saves the previous session automatically, so there is no longer need for the dialog asking if you want to save the current session.
Use "Firefox > Quit Firefox" if you want to restore multiple windows.
You can use "Firefox > History > Restore Previous Session" to get the previous session at any time.
There is also a "Restore Previous Session" button on the default about:home Home page.
Another possibility is to use:
- Firefox > Preferences > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"
You can set the warn prefs on the about:config page to true via the right-click context menu or toggle the value with a double left-click.

To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.
You can use the Filter bar at to top of the about:config page to locate a pref more easily.
