Xmarks is a commonly used web bookmarking tool that directly competes with Google Bookmarks. Considering that they have some tough competitors, the company has to stay ahead of the curve. Therefore Xmarks recently decided to unleash tab syncing across browsers. It doesn’t matter if you are using Google Chrome, Mozilla Firefox, or Internet Explorer, Xmarks now lets you see the tabs you had open on another session and re-open the same ones again.
So let’s say you have a bunch of tabs open on Google Chrome, then you go to work and you only have Firefox — the tool will still let you open up the tabs you had open at home on Chrome. To get the process started, go to my.xmarks.com from any browser and make sure that you have tab syncing enabled in the options. To see the tabs you had open on mobile browsers, there is a shortcut that appears right away that says “Open Tabs” and on desktop browsers, you can click the Tools menu to select the Open Remote Tabs window.
