Hello StevenCee,

When you click on the plus sign (<big>+</big>) to the right of the tab you are on now, it will open the New Tab page that shows your Top Sites. That plus sign is the only icon you need .....

You can create a new bookmark on the Bookmarks Toolbar and set the location to about:newtab or to about:home to open the default Firefox Home page or open the about:newtab page and drag the tab to the Bookmarks Toolbar to create the bookmark.

That's a helpful workaround, I just wonder why Firefox doesn't have an icon on the toolbar for Top Sites, as some other browsers do, making workarounds, & the extra steps, like this necessary?

Also, why can't we have one site be assigned to Home icon, and something else (like the Top Sites) be opened when a new tab or window opens, as other browsers do? So there's two different ways they can simplify this, yet not either are options...

Did you overlook my post  ?

There is an icon that will take you to the New Tab page with all your Top Sites .....

A new window opens with the homepage(s), so there is no easy workaround possible if you wouldn't set the home page to a blank page (you can use a bookmark and use Shift + left-click).

What is your new tab page setting if you prefer not to use the plus button? I prefer a blank page (I actually use about:about to be able to access other about pages easily).

Yes, I didn't see it, thanks!
