Can't restore lost session from .bak to .js conversion

So I've read the relevant threads here dealing with this issue but either didn't see or couldn't understand a solution.

A number of tabs were lost after a crash and while I have the .bak which does have the information on it and have converted it to .js and put it in the appropriate folder while Firefox is closed, a new .js file is simply created each time and the tabs aren't restored. There is nothing wrong with the about:config settings as far as I know. The file is apparently too large for the online session restore site I tried and I'm not aware of any program to render it legible so that I could recover the information.

Any suggestions would be welcome.

Does it help if you set the startup page?

  • Firefox > Preferences > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"

If you use the Time Machine then you can try to restore a previous version of the sessionstore.js file.

Sorry, yes, the Firefox prefs are set to that. Unfortunately, I don't use Time Machine. (I know, I should).

If they're lost they're lost, but clearly this problem isn't entirely uncommon and there must be some reason for it occurring that I haven't seen anyone identify. When it's happened in the past, I've done the switch with no problem.

I assume there's no way to open a very large .bak file to make it legible enough to actually retrieve the urls?

You can try this post at the mozillaZine forum website.

Thank you again, I came across that earlier and might try it. That's just getting a little over my head. I'm afraid I'll change a setting and not know how to change to back if necessary.

Easiest in the current Firefox release is to open the Browser Console (Firefox/Tools > Web Developer) via Ctrl+Shift+J and paste the code on the command line at the bottom.

Thank you, I'll try that first.
