One of the more usefull extensions! Rated 5 out of 5 stars

When I first looked at Xmarks Bookmark and Password Sync the reviews on it were quite mixed. Despite many "horror story" bad reviews there were enough good ones to peak my curiosity. I decided to give Xmarks a try. I'm glad I did. Shortly after installing the extension I had a severe problem that required replacing my main hard drive. I had to go through the hassle of a complete system reformat. Even if you have your data backed up this procedure can be a royal pain in the butt. However, when it came time to reinstall my bookmarks I simply pushed a couple of buttons, waited a few minutes, and SHAZAM ...... My bookmark toolbar reappeared with all 25,000 + bookmarks in the folders, subfolders, and sub subfolders just as I had organized them. Everything was in place and completely up to date. I couldn't ask any more of Xmarks. Simply put, it worked perfectly in a crisis.

This review is for a previous version of the add-on (3.4.6).
