Hi. I have done a cleaning with CCleaner, so not sure if it affected firefox, but now the new tab page doesn't have my shortcuts any longer nor any buttons to add them. I had 4 rows of my most used ones. Now I only have the "recent activity" 2 rows....but they don't seem to fill in either...not sure what went wrong. in my settings the shortcut button is ticked. Is there a way I could revert to firefox that I had a couple of hours ago, to see my shortcuts back? I am not technical, so don't know what to do. thanks.
