I'd like to recommend you a new and great visual bookmark addon that I've been using.

It is not without reason that GroupSpeedDial has the largest number of users in its category. It is available for both Mozilla Firefox and Google Chrome and its derivatives. It does import dials from most existing addons, as well as bookmarks / favorites from both browsers.

Its main differential is its repository in the cloud https://group-speed-dial.fastaddons.com/ that allows its operation between devices, be it your TV, Desktop, Laptop, Tablet or Phone.

However, what I most enjoyed about it is that it works with a lot of stability! Unlike the Quick Dial addon I had been using and I gave up afterwards because it had many bugs and froze not only the browser as the whole system very often.

Enjoy!
