Not previous session restored
On start-up Firefox restores (or opens) the last session before I closed Firefox. Or so it is configured. However, since -at least- a month Firefox seems to open the session that it opened the last time and not the session before turning the browser off. I threw out a lot of tabs and rearranged them, but on the next startup everything is exactly as it was before I changed things. This is very frustrating. Why is Firefox not opening the last session that was open (and how it is configured), but a previous one?

Use one of these to close Firefox if you are currently doing that by clicking the close X on the Firefox Title bar.
- "3-bar" menu button -> Exit (Power button)
- Windows: File -> Exit
- Mac: Firefox -> Quit Firefox
- Linux: File -> Quit
You can check for problems with the sessionstore.jsonlz4 file in the Firefox profile folder that stores session data.
- delete sessionstore.jsonlz4 and sessionstore.js
When sessionstore.jsonlz4 is deleted you lose pinned-tabs and open tabs and you will have to recreate them, so if necessary make a note or bookmark them. sessionstore.jsonlz4 is only present in the Firefox profile folder when Firefox is closed.
You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
