I recently stumbled across the extension Toby (Chrome, Firefox), and I'm surprised at how much I love it. So much so that it has replaced the pretty Chrome Delight and Earth View from Google Earth extensions I've been using whenever I open a new tab. I'm one-hundred per cent Toby now, because it's one of the best ways I've seen to get a little more control over all those open tabs in my browser.
I commend those of you who can go "browser zero" — only opening and closing tabs when you need them, rather than using open tabs (and your browser's "pick up where I left off" feature) to just store a never-ending stream of sites that you should check out, but are too lazy to bookmark for whatever reason.
Though extensions like OneTab are also great for helping you keep your browser's open tabs from getting too chaotic, I really like Toby for a few reasons. First, it's a lot more graphical: You create different categories for tabs to live in, like "sites I should really check out," "gaming sites," or "work stuff," and you drop in your open tabs as clickable cards. You can drag these cards around in any order or move them to a different category whenever you want, which is a great way to build a priority list of tabs that, ultimately, can help you reduce the amount of stuff on your "to be visited" list.
Make a Toby account; get advanced features
If you make an account with Toby, not only do you get to unlock the extension's dark mode - my fave - but your tab configuration will also synchronise to the company's servers, ensuring a browser crash won't affect your pretty, organised setup. Toby launches in every new browser tab you open, ensuring that all the sites you've been meaning to visit can keep reminding you that they exist.
You can also add new "note" cards if you need to keep track of some important piece of data or just want to add a little discussion about a particular site or category. Sharing a full category's worth of tabs with others is easy, too, if you want to give your friends a list of all the awesome gaming sites you've been collecting.
