Somehow these are all reasons why I don't like tabs.

Firefox has pinned tab feature and I liked the idea. I could get rid of my go to bookmarks in the bookmark-bar and save a bit space.

But tabs behaved SO differently from bookmarks, I just couldn't stand it. Everything felt wrong and outdated and I had to constanly refresh stuff after I switched back to a tab.

So in the end I went back to the bookmarks bar.
