I lost all my tabs when I closed firefox.
When I close Firefox at night & open it next day. Every tab is lost, so I have no record of the sites I was using. This has happened several times. I am now seriously looking at dumping Firefox due to its very unstable & unreliable performance. Fire fox does not offer any means of reopening all the tabs that it closed, it actually deletes all tracking. Firefox is unstable, unreliable & totally user unfriendly. I am dumping Firefox for a more professional browser, as Firefox is rude & makes it impossible to contact & seek advice. I think Firefox sucks.
It keeps my tabs. Have you tried the setting at the top of the General page in Settings ("Open previous windows and tabs")? You have to leave the tabs open when you exit.
No that didn't solve the problem. What do you mean top of General page. PK
The page may have a different name on your system. It's the first page in Settings and displays when you open Settings.
