I purchased a new Microsoft Surface Pro with a 1 gb hard drive and windows 10 pro. I have downloaded the latest version of Firefox - 55.0.1 (64-bit) and can not get my Firefox bookmarks to import from my old pc. I have tried the Backup - Restore technique and also the HTML technique. Neither works. I get the message box "unable to process the backup file". I also notice that this new Firefox is also not remembering the websites I am going to. When I click the drop down in the url bar nothing shows up. Lastly, Firefox is also running very slowly. As of now I am having to use either google chrome or internet explorer to access the internet. I have tried removing the places.sqlite file and also checked it to make sure it is not a read only file. I have removed and installed Firefox several times with the same results. I can use any help you can give me. Right now Firefox is unusable. The worst part of this is my wife also got the same new Surface Pro as I did at the same time. We also downloaded Firefox to our new computers within an hour or two of each other and her Firefox works fine. I can use any help you can give me. Right now Firefox is unusable and I really don't like IE and am not a big fan of Chrome either.
