The rectangular design of the UI

[theshabang]

The rectangular design of the UI was much better than the current rounded-corner design. You can add an option to switch between the two designs.

Simple: bring back square tabs, URL bar, search bar, etc...

In the future, don't force rounded corners on users.  Make this an option.

Computer monitors and displays are rectangular, I don't understand why UI can't be rectangular, either. It just makes sense. Unless monitors had rounded corners simple UI elements don't need rounded corners. At the very least allow us the option to switch back.

@err2reroor : you can undo it that, but only until Firefox 161 lands on November 24.  Then the "browser.nova.enabled" setting will be removed
