Here’s a strategy that you might consider trying: Prepare some tools which can, at the moment you’re ready, put all those tabs exactly where you need them so you can close those tabs. If most of those tabs are really your to-do list, line them up in one window and then get them into your actual to-do list. I’ve found that if your tools are easy to use, you’ll be more likely to make it a part of your routine.
Justin Lancy has created a great collection of tools to export browser tabs on a Mac. These tools include AppleScripts and downloadable Alfred and LaunchBar extensions, and they support apps like Evernote, OmniFocus, and Reminders – for both Safari and Chrome.
I have installed the Alfred extension to export a list of tabs to Evernote, and it works very well. Check out Justin’s tools for browser tabs here.
