Open Bug 1274607 Opened 5 years ago
From Tree is extremely slow with deep DOM trees, leads to aborted shutdown
STR 1. load testcase 3 in bug 455690: https://bugzilla.mozilla.org/attachment.cgi?id=8754858 in a trunk or aurora DEBUG build. 2. quit ACTUAL RESULT Hit MOZ_CRASH(Shutdown too long, probably frozen, causing a crash.) I can't reproduce it in a beta DEBUG build though, so I'm not sure if this is a regression or something we intentionally do in trunk/aurora DEBUG builds that makes them slow.
