I think it takes up too much screen real estate, and doesn’t add anything to the view.
Right click on tab bar > click on last entry there (forgot how it’s called) and finally uncheck second entry from bottom left.
I think there is an option if you right click the toolbar and the go to customize toolbar

Well it’s not just Firefox, it’s all windows.
Idk about Mint in particular. There’s a way to do this in most de/wm. I would start in the system settings where you can choose light/dark themes. Then just go top to bottom in the system settings.
Sorry I couldn’t help more
Edit: If you don’t go through settings systematically like this often, it’s good practice. You always find things you’ll use later.
Search for ‘Extensions’ in the menu and download Cinnamon Maximus

Pretty sure damn near every Linux DE has an extensions feature.
I’m not complaining about extensions but about “extension to remove”.
I have done that so much more on linux than I did on Windows, lol. It is the Linux way of thinking.
Switch to dwm. https://dwm.suckless.org/
Ah yes, the ever growing and maintained X11 window system.
The future of security and standardization, with the mostly used feature of transmitting GUI assets over a network.
And to top it all off - the most documented code project, with the users facing easy customization options, that requires almost no programming language knowledge - and the easily compatible feature matrix, with allways up to date patch files.
I honestly know nothing about X11 but this reads like sarcasm to me, is it?
Extreme sarcasm. The Free Desktop organization essentially stopped all development of their old GUI solution for Linux - named X11 Window System, and went all in on developing Wayland, the successor.
Plus, speaking as a former DWM and suckless tools user, it is elitist, and thinks way too highly of themselves - they think their code explains itself (which it doesn’t), features are easy to add (nope), and a readable config file is bloat (it isn’t).
I started using dwm for the very reason OP asked. I wanted to remove the window decoration, have a more simplified view, and have full control over what my windows looked like. It works for exactly what I needed/wanted.
