Ryan, have you seen this again? And can your reproduce with firefox started in safe mode? I see you have firebug installed. most of the trunk crashes I see for this signature list firebug.

I hit this today, it is probably a dup of Bug 623351

My crash-stats shows other users of Firebug net panel: http://crash-stats.mozilla.com/report/index/23f6df42-8ad9-4767-90c3-882cb2110107

(In reply to comment #0) > Perhaps I was loading a PHP that was in an endless loop generating new content. > But cannot reproduce it. Ryan, can you try your endless loop with the Firebug Net panel open? We need a reproducible test case (see bug 623351).

I made further tests right after the initial crash and was unable to reproduce it. Haven't seen it for another time.

(In reply to comment #10) > I made further tests right after the initial crash and was unable to reproduce > it. Haven't seen it for another time. then we close WFM. :) However, there remain firefox crashes, and thunderbird crashes per crash-stats bp-d2f5fcbe-d1da-4513-8a06-238482110318 and bp-1704a330-606b-46a0-9d89-252682110308
