You know that nifty bookmark area in Firefox? The one right above the place where all the tabs open up? Well, mine has a fair number of favorite links I can click on, but I find that most of the time I end up opening all of them in a browsing session anyways.
That’s why the Open all in tabs option is so appealing to me. Just right-click in a blank area on your bookmarks bar and click Open all in tabs.
Poof! All of you bookmarks bar links will open at once and you’re good to go!
Note: Google Chrome has a similar option (accessed the same way) called Open all bookmarks. This option, by default, opens each bookmark in its own separate tab.
