two session -> tabs/history lost
Hi everybody, I have been using for years Mozilla and the tabs as a useful productive tool to keep the pages/docs which I was working on, always open and ready to be opened. Every time I closed it, it restored the pages/tabs. Today I opened a second Mozilla session just for 1 page, and I accidentally closed the main one, lately I closed the second one. When I re-opened Mozilla, it restored the one-page second session, and completely lost the tens of tabs and the history I had on the main session.
How can I recover that pages/tabs? Thank you very much
