Yes i have that folder on my desktop.

You need the sessionstore.js file that stores currently open tabs and pinned tabs.

You can use this button to go to the current Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory:
  Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder

that didnt work

Do you mean pages that you have pinned to the about:newtab page?

The tiles on the about:newtab page show the most visited websites by default. To restore tiles that you have pinned yourself you need to check the prefs.js file in the "Old Firefox Data" folder on the desktop and look for the pref(s) that store tiles that you have pinned.

Changes made manually on the about:newtab page are stored in prefs that you can find on the about:config page.

• browser.newtabpage.pinned stores websites that you have pinned to a tile.
• browser.newtabpage.blocked stores websites that you have removed by clicking the X button in a tile.

You can copy the line with browser.newtabpage.pinned to the prefs.js file in the current profile folder.

user_pref("browser.newtabpage.pinned", "[<pinned pages>]");
