A long time ago I was able to set the max number of rows for shortcuts on the Firefox home page to 5. Sometime fairly recently it has changed to 4. I don't know why nor can I remember which line in about;config I used to change it. I think the line was "browser.newtabpage.activity-stream.topSitesRows" but when I try to change it, it does nothing. At the time I first changed it, the max it would change to was 5. The max now appears to be 4 if I did it correctly. Your help would be appreciated.
