Save open tabs in Chrome

Solution 1:

Check out the Session Buddy and Session Manager extensions for Chrome.

Solution 2:

If you right-click a tab, there is a "Bookmark All Tabs..." option you can use.

Solution 3:

I know it's already solved, but if you are looking for an extension that works on multiple computers without the need of sending files over via email or such, then take a look at TabCloud. You can't drag and drop items into groups, but doing it by hand still beats every other extension if you rely on syncing your tabs.

Update: I can't recommend Pinboard.in highly enough. It has this feature among several others.

Solution 4:

I recommend OneTab, as it's a great way to maintain URLs persistently until you decide what you want to do with them.
