I am running Mavericks (10.9.4) on my MBP with Google Chrome (Version 36.0.1985.125).
Anytime I pin a tab, it will stay pinned for the remainder of my browser session. Every time I exit Chrome (clicking on red circle) or quit the application altogether, all of my pinned tabs disappear.
I'm sure you can imagine that this can be quite frustrating: pinned tabs should not disappear. I also do not remember this ever happening on my previous Windows machine. Furthermore, Chrome Help Forums reveal that I'm not the only one with this problem.
Is this a bug or a horrible design feature? Is there any way to ALWAYS keep my pinned tabs pinned, independent of the browser session, via settings or extensions?
EDIT: I've also tried this Auto Pin Tab extension, but for whatever reason, fails to work at all.
