No, I mean that it used to have a down-arrow next to it, and when you would click on it, it would open up a menu that included 4 things you could do (one of which was "Mark This Forum Read", and another was "Subscribe to This Forum", but those are the only two I remember.)
Now, when I have the menu like it shows in the thumbnail attached to my OP, I click on "Forum Tools" and it takes me to a section at the bottom of the page, below the thread listing, and the four links are there.
However, when I use THAT "Mark Forum Read" link, while it does indeed mark the forum as read, it also takes me back to the main FT page with the list of all the different forums I can go to. Then I have to navigate back to return to the forum I was in. The old functionality would just mark all the threads in that forum as read, and leave me in that forum.
Note: Since I've posted originally, sometimes I will get the Forum Tools with a drop-down menu, and sometimes I get the "new" forum-tools-at-the-bottom-of-the-page functionality.
