In Firefox, when I am on a pinned tab and type a different link in the address bar, Firefox opens the new link in the same pinned tab, thus losing the original link.
This does not happen in Safari, for example. In Safari, when I type an address from a pinned tab, the new page opens in a new tab, preserving the original address in the pinned tab.
I would greatly appreciate it if this feature could be included in future versions of Firefox.
