Only copy the files that you really need to that new profile.

Thank you, I managed to save my bookmarks. However I still can't restore the tabs.

Where are the tabs in Firefox 4 stored? Can I just copy my sessionstore.js from an old firefox 4 profile folder into the new one and see my tabs again? I can't get it to work.

Tabs are stored in sessionstore.js

Thanks, it didn't work though.

I copied the sessionstore.js from my old profile to the new one. When I opened firefox, it turned the sessionstore.js into a 10 byte file. I guess that's an empty file.

I think my sessionstore.js is corrupted. Can I manually extract all the tab urls from it? Is there an easier way besides using wordpad to pick them out, as I have quite a lot of tabs.

Thanks, how do I do that? Do I copy the sessionstore.js into my firefox 4 directory then type that into the url bar? Because once I open firefox the sessionstore.js turns into a 10 byte file at that point.

You can drag the file in a Firefox window or open the file via File > Open File (or Firefox > New Tab > Open File)

After the file is loaded (you see it on one long line) then you can paste the bookmarklet code in the location bar and press the Enter key or click the Go button.

A new tab will open with the links if the bookmarklet was capable of extracting them.

Thank you, I will try that!
