Firefox sessionrestore recover how to#
You can close the tab and try again in a new tab.Īfter identifying the file that makes the most sense to restore, we can suggest how to swap it with the file Firefox will look for at startup. Note: If the script doesn't give you a list within 15 seconds, the tab probably crashed. You can use the Save List button to archive it as a locally saved HTML file in case other methods of recovery are not successful, or in case you don't actually need all of those tabs at once. You can drag and drop it onto the box and after Firefox extracts its contents, click "Scrounge URLs" to generate the list. I have a tool to generate a list of the tabs in a session history file. Hopefully you saved a backup copy of those files to preserve them - as you noted, Firefox regularly updates them. If so, how could I get Firefox to use it when I next open it? (assuming if I close this browser it won't overwrite the "previous.jsonlz4" file?).Īlso could I use the upgrade.jsonlz4 file to try to restore all the windows and tabs that I lost? The windows would have been much the same on 12 Feb as they were today before the destruction. Is it possible "previous.jsonlz4" may have all the windows and tabs that I lost? Recovery.jsonlz4 19:10 (this file changes its name from bak to json and back to bak again, very odd) Trying to sort it out using restore all tabs and then all windows, it just made the problem worse and the restored tabs eventually stopped restoring so now I have useless json files. It just opened one window with the Home page. Firefox (97.0 64 bit, windows 10) destroyed all my previous tabs (4 windows lots of tabs) when I opened it despite always having "Firefox will" set to "Remember History".
