Firefox extensions can’t mess with Firefox tabs. Sure you have extensions such as tree style tabs but they don’t really change the tab bar, they add side-panel with your tabs in a tree style format. This means you end up with a tab bar and a tab panel, which is a bit clunky. There are ways to hide the tab bar by messing with the userChrome file but that’s not user friendly at all.
I don’t have any particular setup that is too outrageous or different from anyone else. I just use Firefox, whatever is the most recent version in the arch repository. Ocasionally I open the browser and I don’t have any pinned tabs, I don’t know why. It’s not a frequent event or something tied to anything I can think off, it just appears to be random.

In C++? I’d rather be shot, thanks :P
