I wish I could edit my question (above). It should say "the arrows are now facing or pointing to the right.

I want the menu and bookmark arrows to face or point left side (as they were) but something changed and now they face/point right. How do I change it.

Is this about to what side the drop-down menu opens?

Firefox would normally open menus to the right, but if there isn't enough space available or if there are long lines then menus open to the left.

Thanks for the input. However, it makes more sense that the menu from bookmark tab would drop down and the arrows would point left of the tab because there is more room on the screen to center and left. (as I'm facing screen, it would be to the left)

The bookmark menu (until today) always displayed menu ARROWS to the left - not the right.

Hi, that can be influenced by a long bookmark title - try right click > Properties to shorten any recent long ones.

Yes, I did shorten recent "long" titles. I hope when I reboot the arrows will point to the right/center again. I have my doubts.

Well, I think I solved it. I disabled an add-on that I had just installed.

Bookmark menu back to normal. It would be funny if it weren't so frustrating. (firefox)
