Firefox 6 doesn't keep tabs saved has Firefox 3 does. I was also used to use this feature Firefox 6 has at the Historic menu the Restoring Previous Session option which is not the same. I put a question related to this subject [[https://support.mozilla.com/pt-PT/questions/872761]]

Firefox now automatically saves open tabs when closing. When you re-start Firefox, do one of these: #Restore from History: #*click ''Firefox button> History > Restore Previous Session'' #*click ''History > Restore Previous Session'', if using the Menu Bar #Restore from the about:home page: #*type '''''about:home''''' in the Location/URL bar and choose "Restore Previous Session" #*See https://support.mozilla.com/en-US/kb/common-questions-after-updating-firefox#w_why-werent-my-tabs-and-windows-restored #Change your home page setting: #*Change Options > General tab, change "When Firefox starts:" to "Show my windows and tabs from last time" #*See [https://support.mozilla.com/en-US/kb/Options%20window%20-%20General%20panel Options window-General Options] IMPORTANT: *You must close Firefox using ''Firefox button > Exit/Close'' (or ''File > Exit/Close'' if using the Menu Bar) for this to work properly *You must have "Remember my browsing history" selected; click ''Firrefox button > Options > Privacy'' (or ''Tools > Options > Privacy,'' if using the Menu Bar'') **See [https://support.mozilla.com/en-US/kb/Options%20window%20-%20Privacy%20panel Options window-Privacy panel] *You must not clear "Browsing History" when closing Firefox; click ''Firefox button > Options > Privacy > [X] Clear history when Firefox closes > Exceptions > [ ] Browsing History'' (or click ''Tools > Options > Privacy > [X] Clear history when Firefox closes > Exceptions > [ ] Browsing History'', if using the Menu Bar) **See [https://support.mozilla.com/en-US/kb/Clear%20Recent%20History#w_how-do-i-make-firefox-clear-my-history-automatically Clear Recent History - How do I make Firefox clear my history automatically] *You must not be using Private Browsing or start Firefox in permanent Private Browsing **See [https://support.mozilla.com/en-US/kb/Private%20Browsing Private Browsing] **Options > Privacy > [ ] Permanent Private Browsing Mode ***See [https://support.mozilla.com/en-US/kb/Options%20window%20-%20Privacy%20panel#w_use-custom-settings-for-history Options window-Privacy panel-Use custom settings for history] '''If this reply solves your problem, please click "Solved It" next to this reply when <u>signed-in</u> to the forum.''' ------------------------- Not related to your question, but...

Why in HELL didn't Firefox tell us about this ridiculous "new" way to restore previously opened tabs?? Good Lord, give us the info window again, or at least have the option to put a 'button' to click to restore.
