Session restore crashed. changing sessionstore.bak to .js not working.

Question

I've tried every guide out there to no luck. I've tried changing my sessionstore.js to sessionstore.old then changing my sessionstore.bak to sessionstore.js. Must be corrupted and not working. Tried using many different guides such as http://forums.mozillazine.org/viewtopic.php?f=38&t=622036&start=60. Tried this method from that link
"Here is an example that works for me in scratchpad in the browser environment.
Instructions:
1. open about:config
2. set devtools.chrome.enabled to true
3. tools > web developer > scratchpad
4. environment > browser
5. edit > paste (i.e. copy and paste code below)
6. execute > run
or
1. tools > web developer > error console
2. paste code in text field
3. evaluate code"
Not familiar with all this code tried to follow many instructions from many different posts. Nothing works or I'm simply not doing the steps correctly. Tried using different settings/programs and extremely frustrating to the point where I want to break my laptop.
Can anyone write a guide and explain it like I'm 5. Step by step to help me restore my tabs from this corrupted sessionstore.bak file.

Answer 1

You would have to open the sessionstore file in a Firefox tab or text editor and copy and paste the text in the text area on the JSON validator web page, but with a 2 MB file size the file is probably too large to get accepted (the limit might be 1 MB).
Do any links come up if you copy the sessionstore.bak file to sessionstore.bak.txt and open this txt file in a Firefox tab and run the below posted bookmarklet code (i.e create a new bookmark with the code and click this button)?
You need to create a bookmark (e.g. on the Bookmarks Toolbar) and paste the full JavaScript in the location field. You can give the bookmarks a name like JSON
<pre><nowiki>javascript:(function(){var D=document,H,i=j=0,P=D.getElementsByTagName('pre'),t=[],R=/[^:]\{"entries":\[\{("url":"([^"]*)")\,("title":"([^"]*)"){0,1}/g,T,U;for(j=0;E=P[j];j++){H=E.innerHTML;while(R.exec(H)){U=RegExp.$2;T=RegExp.$4;if(T.length==0){T=U;}t.push('<b>['+(++i)+']</b> <a href='+U+'>'+T+' ('+U+')<\/a>');}}with(window.open().document){write(t.join('<br>\n'));close()}})();</nowiki></pre>
