Firefox can not synchronize bookmarks, the solution to the failure to restore backup files

Two days ago, the notebook reinstalled the system. After installing the system, install the Firefox browser. After installing the browser, log in to the account. Login is normal. Try to synchronize bookmarks, but there is no response:

Fortunately, there is also a desktop. Firefox login is normal, export bookmarks.html, send to notebook

On the notebook, Firefox my footprints, select [Import and backup]-> [Import bookmarks from HTML] Select bookmarks.html, no response.

Enter a URL in the address bar, which can be opened normally and cannot be bookmarked.

Desktop firefox, my footprints [Import and backup]-- > [backup] back up the bookmarks-2018-12-04.json file and send it to the laptop

On the notebook, Firefox my footprints, select [Import and backup]-> [restore] Select bookmarks-2018-12-04.json, and pop up [unable to process backup files].

Treatment method

Open the user configuration folder for Firefox

C:\ Users\ UserName\ AppData\ Roaming\ Mozilla\ Firefox\ Profiles

Where Username is your own user name

Next, close the running Firefox browser.

Find the following three in the open folder with "places." The beginning of the file (if any)

Places.sqlite

Places.sqlite-shm

Places.sqlite-wal

Delete the above three files

Restart the Firefox browser, the above three files have been reproduced, and the bookmarks have returned to normal!
