Windows had fallen into BSoD taking all tabs away

Recently I had my laptop go BSoD. After I restarted Windows and launched Firefox, I realized that all of my opened tabs, carefully sorted into groups weren't there. I googled some info about this issue and found out that all previous sessions are stored in sessionstore.bak / .js files. So I downloaded Recuva and searched for those files in my firefox profile folder. Fortunately, most of them weren't corrupted, so I was able to recover them. They hapened to be significantly larger, than current sessionstore file, so i felt like a hunter :) My question is simple: How do I "feed" at least one of tose files back to firefox? I tried replacing existing one, but browser kept overwriting it. What should I do?

Nice a hunter! Happy to help, the file that is current is the sessionrestore.bak file. Or at least that is the one that is loaded. You will want to rename the session.js file to sessiontest.js and copy the one you have in the .js format. Then open about:sessionrestore and the tabs should show up.

Did this help?

You can check the sessionstore files and open the file in the Scratchpad (Firefox/Tools > Web Developer).

Sorry, still nothing. Maybe my hands grow from wrong place or somthing, but neither Scratchpad nor session-file approach had result( I didn't even find session.js file, since there are only sessionstore.bak and sessionstore.js. Replacing both of them with old version of sessionstore.bak (and/or renamed to .js) didn't result in anything than completely new session and empty about:sessionrestore page. Here is screenshot of my profile folder if that can help...

Are you using any extensions that deal with session storage as I see a Sessions folder in the screenshot?

To restore a session you would have to use "Show my windows and tabs from last time" for the startup setting.

Did you check the content of the recovered sessionstore files because it is not enough if Recuva shows that recovering is possible and have been done successfully?

I installed an extension during my attempts to recover session, but it did not help, so I just removed it. No, I didn't check content of the files. How can I do that?

I wrote that above in one of the replies.

There should only be plain ASCII text in the file.
