After crash all the recovery files were gone. With a recovery software I could get old versions of recovery files (recovery.bak, recovery.js). I try to implement them in the new profile folder by exchanging the files, but FF34 just ioverwrites them. Unfortunalty I could not restore the old sessionstore.js file. Any idea how I can restore the ols session with this 2 old files (recovery.bak, recovery.js)?

Did you check in a text editor that the recovered files are not corrupted and only contain ASCII text?

You would have to copy such a recovery file to the main profile folder as sessionstore.js to replace the current copy.

If you do not use "Show my windows and tabs from last time" then you need to use "History > Restore Previous Session" and possibly "History > Recently Closed Tabs/Windows".
