###!!! ABORT: should not get marked modified during parsing: '!data->mSheet->IsModified()', file layout/style/Loader.cpp, line 1748 Could this be a regression from bug 185236?
Yes. The bug is in the assertion itself, though. The issue is that the appendChild call in this case will go ahead and create a new stylesheet which is all set to go. It will also post an async SheetComplete for it. Then the very next line of script will modify the sheet. The assertion just needs to move into the !mSheetAlreadyComplete block.

Comment on attachment 564116 [details] [diff] [review] Don't assert that sheets are not modified when it would be just fine for them to be modified. I believe we should take this on aurora. It's a very safe change (debug-only code moving around), and will keep this bug from getting in the way of Jesse's fuzzers.

Hi guys. In order to verify this bug, it's enough if I load the test case from the attachments and observe that Firefox isn't crashing? Thanks
In a debug build, yes.
