Windows 7 - I deleted firefox and didnt save my bookmarks!! I need them!!

I had 2 versions of firefox on my pc, and both had bookmarks. So i deleted one program and when i opened the other firefox there was no more bookmarks!! How do i get them back? I managed to use get data back and it found the back up Json files but it wont accept them? when i use a json viewer in firefox to view the backups i get "There was an error parsing the json document. The document may not be well formed.'' I really only need a few sites back but stuck now?

Try a system restore to a point in time before you deleted your other version of Firefox, and then make sure you save your bookmarks to an external source before you delete it (Firefox) again.

i have a ssd and restore is off

You could try Recuva, but once again you need an external source to save any recovered files to.

Your other alternative is a professional data recovery service, but they are very expensive.

Welcome there may be one last resort before the recovery service. A bit like using atomic weapons to kill a fly, but how about a system image.

I did use get data back and found json backup files but can not read them or know what to do with them.

If the data is corrupted I guess you've lost the files unless you are prepared to pay a lot of money to get them back.

Can you now see the value of system restore and regular backups?

I just woke up this morning and was reading this post......
Why not download FF and sign in under your old account and pluck those addresses/contacts then transfer to
a stick and then uninstall FF?

Or do I need more caffeine to be up to speed?
THW

I'd say your caffiene levels are fine, Dennis.

Seems like a good solution to me.

What do u mean sign in? i never had to sign into anything for firefox?
