Isn't that about the normal behavior when the Back button is enabled (i.e. there is tab history) ?

Thanks, cor-el, for your reply.

The arrow is boldfaced when the tab has a history. I'm asking about the boldfacing of the circle surrounding the arrow.

are you talking about the colored button with an arrow drawn on it?

What I'm referencing is the back arrow. (I believe what I have is the default, but maybe not.) It's the arrow pointing to the left, to the left of the locbar, next to the left edge of the browser. It's accompanied to its right by the forward button, both of which precede the locbar.

Are you using a theme other than the default theme? Neither the default theme here nor the theme I am using has a circle around the back arrow.

TerryN21, upon reading your post I have switched to the default theme, and there is still a circle surrounding the back arrow.
