Hello, on the 24th, I had opened a new tab to search something, like normal. It wasn't loading, so I closed my window of 20 or so tabs to reload the browser. When I reopened the browser, none of my tabs were there, and the "recently closed windows" option wasn't available in the three lines menu in the top-right of the browser page. I cannot search for all of these tabs individually in my history, as some of them were saved from many months ago. But I needed these tabs open to refer to them for work. I saw a page describing how I could reload my last session from C:\Users\[username]\AppData\Roaming\Mozilla\Firefox\Profiles\khv448gm.default-release\sessionstore-backups, but those files had already overwritten with the session that didn't have any tabs. I looked through the "Previous Versions" tab in properties, but it only had previous versions of the folder from earlier that day, and not before I had closed the browser. I asked my IT department at work if they were able to load a previous version of the folder for me from before the 23rd, but they just redirected me to Mozilla support first. My question is, is there any way I can restore all my old browser tabs? Or is there anywhere else I can look on my computer for locally stored previous sessions from before February 24th? Thank you!
