This ids how to fix Xmarks .... Rated 5 out of 5 stars
Xmarks did not work anymore since I upgraded Firefox to V56.
Strangely, to revert to an older version of Firefox and Xmarks did not allow to restore the operation of Xmarks.
Here is the procedure I followed on PC:
In Windows Explorer, locate on C: and search for the keyword "firefox" and then delete all the results
Clean Registry with Ccleaner
Download an older version of firefox from the following link. I have chosen version 54.0
Install Firefox 54.0
Start Firefox and immediately block the automatic update of Firefox by changing the settings in the Advanced Options / Updates
Download the version 4.3.15b2 of Xmarks (xmarks_sync-4.3.15b2-sm + fx.xpi) from the following link
Install in Firefox the previously downloaded xpi file using the "install a module from a file"
Ask Xmarks to upload your bookmarks to the server instead of your favorites on the computer
There you go !!!!!
