Visited pages shortcuts

This is probably more a suggestion than a question. In the "Home" section of the settings under "Firefox Home Content" there are two different settings for creating shortcuts for pages you visit - one under the choice of "Shortcuts" (on/off) and then just below that there is another choice for "Recent Activity" (on/off) with a sub-menu (on/off) choice for "Visited Pages". I realize these are two different things (logo thumbnail for the first/webpage images for the second). But I find it not only redundant, but since I don't want to clutter my home page with recent visits, and I only chose the first shortcut setting, every time I visit a site, that is now added to the icons that I HAVE chosen. And worse, when I delete one, a new one pops up in its place, sometimes four or five or more times, whether I "Dismiss" or "Delete from history". It seems to me that there should be a choice for "Sites visited" in the Shortcuts choice or not include that at all. The only way to s top it is to fill up the rows. I'm getting there but until I do, I keep fighting with these new shortcuts popping up on their own.
