more options

Today, my firefox window crashed along with over 15 hard to find tabs for a research paper. I need to manually restore those tabs. I do have a previous.js file which corressponds to all teh tabs I need, but I have no idea how to use it. I currently use the latest version of firefox and Mac Os X yosemite.

Hi When you select Restore Previous Session from the default home page

After restarting with add-ons disabled

When you restart with add-ons disabled to troubleshoot Firefox problems, your tabs and windows will be reopened. After a crash

Due to unexpected issues such as problems with a website, software errors, or an accidental loss of power, Firefox may unexpectedly close. In these situations, Firefox can restore the pages that you were visiting when it is restarted. Firefox will automatically restore your previous session, the first time you launch it after a crash.

If Firefox crashes a second time, the Restore Session (i.e. "Well, this is embarrassing") page will appear when you next launch Firefox.

   To restore your previous session, select the windows or tabs you want to restore and click Restore.
   If Firefox continues to experience errors when windows and tabs are re-opened, you can launch Firefox without restoring these items. Click Start New Session.

You can set Firefox to always show your windows and tabs from your previous session each time you start Firefox. To change your Firefox startup settings, see Configuring session restore, below. Configuring session restore

You can make a backup copy of the previous.js file and the other files in the sessionstore-backups folder elsewhere. You can copy the previous.js file as sessionstore.js to the main profile folder to replace the current sessionstore.js file. That should allow to restore the session. You may have to check History > Recently Closed Tabs/Windows.

Let me elaborate. This does not show the option to restore the previous window,so I have to do it manually by tinkering around with filenames and what not.

Cor-el I tried what you suggested, it didn 't work out. Any alternatives?

You can open the previous.js file in a Firefox tab.

Open the Web Console (Firefox/Tools > Web Developer) and paste this code in the command line and press the Enter/Return key:

eval("ss = "+document.body.innerHTML.replace("<pre>","").replace("</pre>",""));
sd='';
for (var i = 0; i < ss.windows[0].tabs.length; i++) {
 var ent = ss.windows[0].tabs[i].entries;
 var last = ent[ent.length-1];
 sd+="<a href="+last.url+">"+last.url+"</a><br />";
}
document.body.innerHTML=sd;

Hi ZoravarSingh, I'm not sure whether you found this in your reading, but there's a fine point of timing on the file swap cor-el mentioned. Make sure Firefox is fully closed and has created the new sessionstore.js file before renaming a copy of previous.js to sessionstore.js and dropping it into your profile folder, replacing the sessionstore.js that Firefox created at shutdown. Then at startup, if Firefox is set to restore your previous session automatically, it should use your substitute sessionstore.js. If it is set to start up with your home page, you'll need to use History > Restore Previous Session to have Firefox read the substitute file.
