Every time I launch Firefox 4 it opens 3 or 4 blank windows, no longer opens the tabs from the previous session and does not show my bookmarks sidebar.
I have to manually close the extra windows and restore the tabs from the previous session, and reopen the sidebar. In disgust I uninstalled Firefox 4 and reinstalled 3.6. Everything works fine in 3.6. Looks to me like Firefox 4 has many major bugs and is not yet ready for prime time. I'll stay with 3.6 for now.

Same here, but seems to be increasing the number of windows opened with each restart, last was 50 windows!

This can be a problem with the files sessionstore.js and sessionstore.bak in the Profile Folder
Delete sessionstore.js and sessionstore.bak in the Profile Folder
- Help > Troubleshooting Information > Profile Directory: Open Containing Folder
If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
You will have to redo App Tabs and Tab Groups after deleting sessionstore.js.
See:
In the past week this has happened twice again. I deleted the sessionstore files, everything was ok for a few days, then boom! lots of blank windows, etc. Deleted the files again, went along for a couple days, then boom! again. This time there's a new wrinkle. One of the windows that opens is not blank, it's a window from several days ago for a site I visited briefly.
At this point I am not going to delete sessionstore files, just go back to Firefox 3.6 and wait until there is an update to 4. Obviously 4 still needs work.
