No one? Can somebody at least test on the site with Firefox 42? http://exchangewar.info/coinprice?BTC_BRL

Loading the URL in Firefox 41.0.1 on Linux64 works fine for me. It seems to work fine also in a debug trunk build but I do get this assertion: ASSERTION: aElement should be the element and not the pseudo-element: 'pseudoType == nsCSSPseudoElements::ePseudo_NotPseudoElement || !elementForAnimation->GetPrimaryFrame() || elementForAnimation->GetPrimaryFrame()->StyleContext()-> GetPseudoType() == nsCSSPseudoElements::ePseudo_NotPseudoElement', file layout/style/nsStyleSet.cpp, line 1714

Dâniel, can you crash it again in a debugger and post the values for the local variables there? (pm, pm_end, pr, pr_end and also *this and *aPresContext) Thanks! BTW, if you're debugging this using your default Firefox profile, please make sure you make a backup copy of it first, just in case.

BTW, does it also crash using a fresh profile? The easiest way to test that is to give an empty directory as the profile directory on the command line, like so: mkdir /tmp/x firefox -profile /tmp/x

(pm, pm_end, pr, pr_end and also *this and *aPresContext) > Thanks! Thanks Mats. pm, pm_end, pr and pr_end were optimized out. The problem is that if I recompile without optimization, maybe it will not crash (do you want me to recompile without any optimization to test?).

Does the patch from bug 1196379 help?

(In reply to David Baron [:dbaron] ⌚UTC-7 from comment #7) > Does the patch from bug 1196379 help? Yes! :) Thanks David. I'm marking this as duplicate of bug 1196379. Thank you VERY much!
