versus what the operating system or browser can provide.
In fact, weren't bookmarks supposed to solve EXACTLY this? You'd just bookmark a website on any page then come back to it any time in the future.
But then websites wanted to be apps and stopped storing state in the URL...
But tabs store history, and that's important pretty often to me. And I can dig through multiple tabs and their histories together.
Have session storage extensions ever caught up to where they were before firefox dumped XUL?
Oh yeah, you're right. I do sometimes need the Back button to retain its history, and sometimes duplicate tabs to start a new "breadcrumb" path.
