User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/20120605 Firefox/15.0a2 Build ID: 20120605042007 Steps to reproduce: it appears that due to bug 613588 that has landed in firefox 13, it is no longer possible to open all entries of a live bookmark (either by middle-clicking on it or trough a "open all in tabs"-button) at once. i don't know if this is a regression or an intentional by-product of bug 613588 - in the latter case feel free to close the bug right away.

it's a duplicate of bug 730829. this issue also gets some traffic on sumo, see https://support.mozilla.org/de/questions/928771
