PC crashes

[Nick]

I feel your pain.

Of course, if you used Chrome and were logged into your Google account, then all your bookmarks would be saved in the cloud

You may be able to find your Firefox bookmarks:

• Type in WINDOWS+R
  
• In the box, type C:\Users\\Mozilla\Firefox\Profiles\
  
• See if the old profile is there but has been renamed.
  
• If you find it (or the default if there is only one), copy the data into your new profile name equivalent location.
  

The AppData directory is normally hidden, so you have to unhide it in Explorer or explicitly type the path.

Cheers
