However, when clicking the link "The amazing Fortune Cow says…" to reload the page, the Adsense document is not shown ("partially" refreshed, as the XHTML is dynamic PHP, the HTML page is static, and thusly cached). The Adsense will only correctly be shown again by forcing a refresh of the same page either by pressing <F5> or by clearing the browser cache before attempting to click the link (both dynamic and static content get reloaded). Looking at DOMi, the IFRAME element in the Google Adsense is created via javascript on "clean" load, yet isn't when just "partially" refreshed. The javascript console throws up the following error on "partially" refreshed attempts: Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMScreen.height]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://pagead2.googlesyndication.com/pagead/show_ads.js :: google_get_user_data :: line 55" data: no] onTabLoad: notab tabbrowser Reproducible: Always Steps to Reproduce: 1. Clear browser cache (in the unlikely event you may have visited the site) 2. Go to http://lambcutlet.org/fortune-cow/ 3. Google Adsense banner should show just after "Brought to you by..." 4. Click "The amazing Fortune Cow..." link to reload dynamic content of the page Actual Results: Google Adsense banner does not show, and will only show once a full refresh of the page is done. Expected Results: Behave as per build: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20050921 Firefox/1.6a1 ID:2005092100 ... where the Google Adsense is loaded every time, regardless of how the page was "refreshed". http://jessey.net/ is another website which is using XHTML served as application/xhtml+xml and has Google Adsense inserted via <object type="text/html">. Curiously this does work for him, and the only "difference" is that the HTML page which contains the Adsense code is a PHP page, and hence dynamically generated each time, as it is not cached.

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20050922 Firefox/1.6a1 ID:2005092222 Yeah, I get the same error after clicking the link 7 times or so. Also suddenly this: http://img378.imageshack.us/img378/5442/cow3wi.png

No missing ad in 1.9a1_2005092110. So now the regression date is between 2005092110 - 2005092116. Had to click really a lot of times. :)
I can't reproduce this... are any extensions (eg adblock) involved here?

No adblock, but I do have: * Nightly Tester Tool * Colorzilla * FLST * EditCSS * Google Toolbar * Session Saver
Does this bug still happen if you disable all of those? If so, and if you can create a minimal testcase (still loading google's stuff is fine), that would be nice. If not, which extension causes the issue?
(In reply to comment #8) > Does this bug still happen if you disable all of those? Yes it does, though the javascript console only shows on error: Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMScreen.height]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://pagead2.googlesyndication.com/pagead/show_ads.js :: google_get_user_data :: line 55" data: no] ... the one after in the first comment of the bug report must be related to the FLST extension. > > If so, and if you can create a minimal testcase (still loading google's stuff is > fine), that would be nice. If not, which extension causes the issue? I created a PHP generated XHTML page and still see the issue, curiously though, I did need to load it a few times as per what others have mentioned before the non-display and above console error occured. After a bit of Googling, found a couple more XHTML webpages with adsense loaded the same way, exhibiting the same effect: http://www.workingwith.me.uk/ and... http://www.neothermic.com/ I think I was seeing the "effect" sooner with normal browsing as I generally have a boat load of tabs (30+) open at any one time?
Oh, so this isn't reproducible the first time you reload the page (per comment 0, it sounded like that was the way to reproduce)? Again, as small a testcase as possible that shows the problem would be much appreciated....
(In reply to comment #10) > Oh, so this isn't reproducible the first time you reload the page (per comment > 0, it sounded like that was the way to reproduce)? > > Again, as small a testcase as possible that shows the problem would be much > appreciated.... When I was trying out various things, having less open tabs at the same time seemed to require whatever problem page to be loaded more times before the javascript exception came up (which halts the Google ad being shown). I've hosted a dynamic base page here: http://lambcutlet.org/files/test-cases/adsense-object.php ... for those that care what (little) PHP there is, see here: http://lambcutlet.org/files/test-cases/adsense-object.phps
so I should load that page, hit reload a couple of times, and eventually see the ads disappear?
(In reply to comment #12) > so I should load that page, hit reload a couple of times, and eventually see the > ads disappear? Click the "self referencing" link: adsense-object.php Hitting reload doesn't (so it seems) cause the bug to appear as the HTML object is reloaded as well.

Can anyone on windows reproduce this with a debug build?
can't reproduce in seamonkey/windows :( OK, does this happen in a new profile as well?
with a firefox nightly zip build on windows I can't reproduce this either :( (clean profile, no extensions)
(In reply to comment #16) > Can anyone on windows reproduce this with a debug build? I can try with a debug build if I knew where it such builds exist for Win32? Building from source ( http://gemal.dk/mozilla/build.html ) is rather out of the question for me due to slow Internet connection and what not.
A debug build would be on the order of a gig or more in size, so building it is about the only way to get one...
(In reply to comment #20) > A debug build would be on the order of a gig or more in size, so building it is > about the only way to get one... That rules that idea (downloading it) out then. :)
For whatever reason, I can't reproduce this bug consistantly anymore on the initial reported page, with Firefox build: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20051012 Firefox/1.6a1 ID:2005101221 However, I do still see the same non-advert loading and script error with: http://www.neothermic.com/ (Google ad on the left bar) *beware, slow page with lots of (work safe) thumbnail images... http://lambcutlet.org/blog/2005/09/29/2005-tai-hang-fire-dragon-dance-photogasm/ (Google ad just before the comments at the bottom) Same old error... Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMScreen.height]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://pagead2.googlesyndication.com/pagead/show_ads.js :: google_get_user_data :: line 56" data: no]
so does this work in a new profile or not?
hah! Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMScreen.height]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://pagead2.googlesyndication.com/pagead/show_ads.js :: google_get_user_data :: line 56" data: no] now if only that had been a debug build... (this was on neothermic, with a firefox nightly, new profile)
(on winxp) I'll make a firefox debug build, I guess...
(In reply to comment #24) > hah! > Error: uncaught exception: [Exception... "Component returned failure code: > 0x80004005 (NS_ERROR_FAILURE) [nsIDOMScreen.height]" nsresult: "0x80004005 > (NS_ERROR_FAILURE)" location: "JS frame :: > http://pagead2.googlesyndication.com/pagead/show_ads.js :: google_get_user_data > :: line 56" data: no] > > now if only that had been a debug build... (this was on neothermic, with a > firefox nightly, new profile) Phew... thought I was going mad! Look forward to seeing what's the cause of this quirk.
Attached file debug build output —
hm, not sure the debug output is much help (btw, this is really hard to reproduce, happens very rarely) I should probably set some breakpoints next...
Attached file stack + member vars —
nsScreen members: - mDocShell is not null - mDocShell->mContentViewer is not null either - The content viewer's device context is null, though So are its pres shell and its pres context. - the docshell's bounds are all zeroes
doCreateDocShell is only called after the script runs and accesses window.height
Attached patch Patch to try (obsolete) — — Splinter Review
Per debugging with biesi, we think this should work. Biesi, does this fix things for you?
unfortunately this doesn't help :( the prescontext is still null, and therefore I still get the assertion.
there was no same type parent of the docshell in nsDocument::FlushPendingNotifications... so doc->FlushPendingNotifications wasn't called. however, a presshell was available, and its FlushPendingNotifications was called. It looks like the docshell's parent has an item type of 0 while the child docshell has a type of 1. I have no idea if that is relevant... (that parent docshell is, I suppose, the browser docshell.)
> there was no same type parent of the docshell in > nsDocument::FlushPendingNotifications... so doc->FlushPendingNotifications > wasn't called. however, a presshell was available, and its > FlushPendingNotifications was called. Right. That would be expected. This FlushPendingNotifications on the presshell didn't construct the nsSubdocumentFrame? > It looks like the docshell's parent has an item type of 0 while the child > docshell has a type of 1. Right. The parent is the browser chrome, while the child is our content tab... At what point _was_ the subdocument frame constructed?
it was constructed during the parent document's InitialReflow, triggered by the end of the document load. So things are fine when the script executes only after the main document has finished loading.
While this is, technically, a regression of bug 1156, it's not really caused by that... <iframe>s should be broken even before that bug. all a consequence of the non-incremental XML content sink. (some of those conclusions above are bz's :) )
This is basically bug 18333 -- when we need a layout object for the <object> it's just not there, since the parent is not done parsing yet and hence InitialReflow hasn't happened. Note that we've had the same issue with <iframe> in XHTML since forever, and .screen will reliably fail in a display:none object or iframe no matter what we do...

Ever confirmed: true
Though this bug still affects build Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20051108 Firefox/1.6a1 ID:2005110821, I guess it can still be closed as it's a duplicate of bug 18333?
No. It's a separate bug. Fixing bug 18333 might not fix this, but it'll make it possible to fix this.

per comment 31 this didn't fix the testcase. why was the bug resolved?
Yeah, this should be open until it's actually fixed.

This worksforme now.... Jonathan, are you still seeing it with a trunk build?
Yup, I see this as resolved on the following trunk build: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9a3pre) Gecko/20070302 Minefield/3.0a3pre ID:2007030205 [cairo]
Marking worksforme, as per comment 48 by the reporter. If someone can still reproduce this on trunk, please reopen.
