Hi, is Firefox crashing completely and closing or do you get an in-tab crash message ("Gah" and button to reload)? Usually Firefox will attempt an automatic crash recovery for a regular (non-private) session. If Firefox isn't automatically restoring your previous session windows and tabs, could you check whether either of these are available (not hidden or grayed out): * "3-bar" menu button > History > Restore Previous Session * (menu bar) History > Restore Previous Session If they are missing or grayed, check either: * "3-bar" menu button > History > Recently Closed Windows * "Library" toolbar button > History > Recently Closed Windows * (menu bar) History > Recently Closed Windows ---- When you reload after a crash, Firefox normally only restore the active tab in each window. Then when you activate other tabs, Firefox loads them. So it should be a while before Firefox is overloaded, if that's the problem. Assuming you're back up and running, could you describe the message you got in more detail? If you have a lot of tabs open just to remember them and not because you need them in the near future, you can create a giant bookmark folder of your open tabs. Either: * Ctrl+Shift+D * (menu bar or Alt+B) Bookmarks > Bookmark All Tabs... You can give the new folder a name like '''6/23/25 Tab Backup''' so you can remember the purpose of it later. ---- If you had some other question about tabs, maybe describe how you like to use them?
