That is how technologies become popular, but the process is symbiotic: culture changes from technologies also.

For example, mobile phones became popular because they were culturally compatible: we wanted to be able to contact anyone from anywhere, and this technology met that need. As mobile phones gained usage, culture shifted because of it: we started messaging more frequently in text, we started ignoring the world around us when we wanted to use our phone instead, possibly our attention spans decreased, etc.

These changes are not "decided upon," but derive from the way technology meets our needs. Our culture shifts through our technology use. But sometimes, our cultural needs aren't fully met by technology. Those who feel socially isolated yet communicate plenty via the internet may feel some of this. Just as our physical needs prompt technology, our cultural needs can do so as well. It's a process that goes on whether or not we're conscious of it, so being conscious of it, I'd argue, is important.

It isn't bundled now, but will be soon

True, but using a built-in font does mean Firefox is consistent across operating systems. Unfortunately, it's tough to be consistent across both OSes and applications within an OS!

I believe you can't using the Customize UI, but for a hacky solution you could add spaces in bookmark titles, like this: http://cl.ly/image/2Q2b3L3c061a

You can add another bar in the customize menu and put add-ons on that bar, if you prefer!

Actually, you can do this in Firefox 29! Click the Customize hamburger-button on the right and then click "Customize." Drag the search bar from the menu bar down to the tools page. Then drag "Bookmarks Toolbar" up next to the URL bar. It should display as your bookmarks, listed next to the URL bar. Here's how it looks on my machine: http://cl.ly/image/1M3N3L0h3v1s

Thank you!

Nah, just Firefox 29. I was channeling Heraclitus.

Thanks, Damian! Posting to my own Wordpress and then going to sleep was, retrospectively, a poor choice.

Absolutely right on same space but illusion of more. It's amazing how much small tweaks can make a difference in perception of visual space and faster action: bigger targets, whether actually bigger or seemingly bigger, make users faster in hitting them.
