There, I started reading the page [during its rendition, though not sure if it may have completed], and a mouse scroll at 8 14 caused a crash. I went back to the moz support page after the start up, and at 8 21 forced the crash, again, using the vert. scroll bar. I had deliberately waited for rendition to complete, and to the best of my knowledge, it had. I can -not- attribute the following to the crash, but many lines of this notation appear on the error console: Warning: Expected declaration but found '*'. Skipped to next declaration. Source File: http://support.mozilla.com/minify.php/css_styles_mozcommon;css_styles_mozfr Line: 1 Reproducible: Sometimes The crash occurs in standard mode, I have not duplicated this, yet, in safe mode. I am using the startup profile, not a new one. This pattern of crash occurs frequently enough to annoy, where I scroll and a crash occurs. These crashes occur with both a mouse scroll and a vertical bar scroll. This is not a constant thing, but happens now and then during the day. Has happened in prior Fox versions, as a problem that appeared with new version [sorry can't be specific right now]. No other software has a scroll-associated crash. Prior bug filed in this Fox version as Bug 546859. Bug report Prior Ver 3.0.8 https://bugzilla.mozilla.org/show_bug.cgi?id=486232 -- this bug reported wide range of crash type, including the scrolling. My current intuitive sense is now this is a rendition problem, which scrolling catches more often, and sometimes just happens without scrolling.
So you are saying this is the same as bug 486232, just more details? Or what? Also, you say this doesn't happen in safe mode? try a new profile then to double check.

On filing the above bug report, I closed all Fox tabs/windows except the support page, and closed yahoo/aim, and then went to the support page. Scrolled. Crashed at 8:57am. Then opened in SAFE MODE, and that support page loaded fine, and appeared happy with scrolling, and then used the scroll bar, and scrolled up/down, dragging the bar at .75-1 sec intervals, and it crashed at 9:01am SAFE MODE CRASH: bp-095fa8dd-9cd4-456e-841c-7c6ca2100219 2/19/2010 9:01 AM Another Std Mode crash: bp-d44d136f-8b7e-4cb7-97ec-218582100219 2/19/2010 8:57 AM ------------------- Additional Info on Error Console: No new errors related to the support page that caused the crash However, these two sets of errors show in two repeated piles: Warning: Error in parsing value for 'white-space'. Declaration dropped. Source File: https://bugzilla.mozilla.org/skins/standard/global.css Line: 278 [and 7, 278-280, etc., also for calendar.css at line 7] Warning: Unknown property 'zoom'. Declaration dropped. Source File: http://crash-stats.mozilla.com/css/screen.css Line: 15 [many at 15, and one at Line 1222] and 4 or so for flora.tabs.css and datepicker.
And now, on thinking, Bug 546859 has the same user feel for the crash [scrolling], except the crash occurred in the layout tables, not the painting background. For that reason, I started another bug. Was this an error, and should it be the same bug or a different one?

Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:22.214.171.124pre) Gecko/20100217 Namoroka/3.6.2pre I tested this quite some times even with Tab Mix Plus installed, but was not able to reproduce.
I respect that, but do note that this is not a constant problem; it behaves [there error] almost like there is a timing issue.... i.e.: If I scroll just at the right time, or a secondary page updates in the background that has helper applications embedded on the page [eg: NYTimes.Com]. As I've said, sometimes, I am doing nothing... [other than reading a page which is not scrolling.]
That stack reentering event processing under frame code doesn't look very happy to me....
That's what, Boris ? I'm curious. [" stack reentering event processing under frame code "]
roughly frames 38/39/40 and 19/20/21 are strange. the minidump is available, so someone can ask windbg for more info...
The synchronously-notifying update of 'curpos' in UpdateAttribute is probably causing the problem here. Probably need to do it off a scriptrunner. Maybe Mats can look at it...
Robert.... Would you hazard a translation? I'm curious. Though I am an engr. by background, I've no inside experience with the specifics of the Fox engine... Are you saying that there is a timing issue, here? If so, would you think that whatever style of programming that allowed that type error ... exists in the style of other parts of the Fox engine? Though my programming experience is low, presently, in days past, timing issues and software did catch my attention. And I've mentioned my intuitive sense that such a thing is an issue, with Fox, in prior bugs I've posted.
It's not really a timing issue. The issue is that certain kinds of synchronous (notifying) DOM changes are unsafe when executed by certain object methods (methods of ns*Frame classes, typically) because those synchronous notifications can result in destruction of ns*Frame objects.
My sense of what you're saying still aligns with me intuitively -- in that it sounds like you have object methods kill their underlying objects ungracefully. Constructed the phrasing like that [do I have it right?] still implies that there are a broad range of methods that might operate like that, outside of expected behavior, and that there could be a reason to hunt them down....
Do you still see this crash? there are no PaintBackgroundLayer crashes for version 4 since 4.0b8 20101214170338.

Windows xp sp3, INTEl P4 3.2GHZ, 4GB Ram, Intel Perl865 Mother Board. Using FF 16.02 and clicking on the verical scrool bar, using the key board arrow keys or the page up/ down causes a shut down of of my PC and corruption of disk files files as reported by Windows checking disk after unctrolled shut down. This event is potentially damaging to disk since its flying heads do not have a chance to park. Becuse of this I have not done many of the TS steps requested. I have removed FF 16.02, reloaded 126.96.36.199 and it works fine. In addition IE 9 works fine on the same web pages
Reinstalled Windows xp sp3 and Fire Fox 16.02 has no crashes now when using the vertical scroll bars
