Firefox already has sync built-in. I think this is supposed to be an improvement over the current bookmarks system. Mozilla realized that Pocket was already doing that better than they were, so they just integrated it instead of reinventing it poorly.

The old secure Sync was great, absolutely great. I could see all of my bookmarks and history from all of my machines, and it was all well-secured. There was nothing wrong with it.

The main thing wrong with it was that most people couldn't figure out how to use it and hence didn't use it.

This is a common problem with well-secured things (see encrypted email, signed email), unfortunately, which has proven very difficult to solve.

Doesn't it still work the same way?

I see this as Mozilla basically admitting that the extension model has failed; this is a textbook example of an extension, but they've decided that's not good enough.

Exactly! There is already an extension, why isn't Pocket an extension then?

It is. I've been using it for years, they just decided to integrate it with the rest of the browser

That's my point. Why isn't it bundled with FF as an extension, instead of being integrated on the browser and effectively impossible to uninstall?
