Hi Adam

If you right click on the toolbar and select "customise toolbar", you should see a "toolbars" option in the bottom left corner of the screen. Open this and clear the option for "title bar" - this should make that bar you are see disappear.

I hope that this helps.

Thanks for replying! The suggested answer only hides the title of the website opened, not the entire bar. I think it's because it also includes the close, minimize and maximize icons on the left? In that case, I think Firefox needs to be optimized to match Safari on the UX regarding this matter...
