I would have thought that the 25kb one is the one you want, but if it doesn't look right, then it's possibly been overwritten. You could restore it and try it - you have nothing to lose if the passwords are gone anyway.
Bob's thing looks promising, so give that a go as well.
I did start a deep scan Simon, but cancelled it to try Bobs.
Did you download and use the recovery software I PM you the link for? The pro version of Recover4all is capable of recovering your entire firefox profile: bookmarks, cookies, passwords, and so on.
I'm doing now, I've had minimal internet connection tonight. Took me 20 minutes and half a dozen tries to pm you, and I still can't open my emails. At least we're beating the Kiwi's in rugby match on tele.
Why couldn't I use quote for Reno's reply, I tried it a few times and it wouldn't do it, odd? Same as not being able to send a pm to him, coincidence, I'm sure. ':|
