Whenever I click a link in a pinned tab, the link loads in a new tab. If I unpin the tab, the same link loads in the same tab. That wasn't the case before, but I don't know what changed to make Firefox behave this way. I tried disabling all the extensions, that didn't help. I'd like links to behave the same way, whether the tab is pinned or not. Note, I am NOT asking "how to override the default behavior of links and make them all load in the same tab, despite the target attribute or Javascript".
