Accessing innerWidth of a tabbrowser contentWindow throws NS_ERROR_XPC_SECURITY_MANAGER_VETO To reproduce: 0. Fetch a Firefox(!) trunk build 1. Switch signed.applets.codebase_principal_support to true so that a webpage from content can request privs 2. Open any website in the first tab and https://bugzilla.mozilla.org/attachment.cgi?id=238226 in any other tab, make sure you trust the code from that testcase (it's a drawWindow canvas testcase) 3. Click on Draw to get a preview of the page in tab 1 in the canvas below 4. Observe that you get no preview but instead a error in the Error Console: Error: uncaught exception: [Exception... "Security Manager vetoed action" nsresult: "0x80570027 (NS_ERROR_XPC_SECURITY_MANAGER_VETO)" location: "JS frame :: https://bugzilla.mozilla.org/attachment.cgi?id=238226# :: doFrob :: line 26" data: no] Line 26 is a empty line, but by adding some line breaks I found out that it actually seems to mean line 27. This regressed between 2007-07-05-04 and 2007-07-06-04.

It looks like DOMi had a similar problem, see Bug 387053, but that patch was backed out again as Bug 387084 was fixed. So is this now a real bug or a bug in the testcase?
Blake: Can you comment on this bug if it is a valid bug? I'm not sure if it is...
Created attachment 275200 [details] [diff] [review] Fix Given other bugs, I'm rapidly losing faith in EnsureLegalActivity, but this patch will make it deal for now.
Comment on attachment 275200 [details] [diff] [review] Fix OK, I buy this.
Fix checked into trunk.
Don't we need this on branch too? This breaks code using <xul:iframe> (e.g. in signed script). See the thread at http://groups.google.com/group/mozilla.dev.security/browse_frm/thread/200083a2d0cb1562#
And this could really use an automated testcase. Should be simple to mochitest, no?
Comment on attachment 275200 [details] [diff] [review] Fix This patch applies to the branch as well, and fixes the bug there too.
Comment on attachment 275200 [details] [diff] [review] Fix Approved for 18.104.22.168, a=dveditz for release-drivers
Fix landed on the branch.
The mac tinderbox started burning after this bug and bug 418996 and bug 424426 landed on the branch (bm-xserve05). It's failing the Tp2 test: Running LayoutPerformanceLocalTest test ... Timeout = 180 seconds. Begin: Thu Jun 5 18:08:31 2008 cmd = /builds/tinderbox/Fx-Mozilla1.8-Nightly/Darwin_8.7.0_Depend/mozilla/../build/unifox/dist/BonEcho.app/Contents/MacOS/firefox-bin http://localhost/pageload/cycler.html Process killed.

TinderboxPrint:Tp2:[CRASH] LayoutPerformanceLocalTest: test failed cycler.html is here in mxr: http://mxr.mozilla.org/seamonkey/source/tools/performance/pageload/cycler.html?raw=1 Several seamonkey boxes are also having issues: http://tinderbox.mozilla.org/showbuilds.cgi?tree=Mozilla1.8-SeaMonkey&maxdate=1212719731&hours=12 Are these tests broken by the set of changes or has this caught a regression ?
Backed out of branch to see if the orange clears. I'll be watching it over the weekend and will try to reland before Monday.
Relanded, all green.
When can we expect to see this fix in a release version?
Daniel, it's in Firefox 22.214.171.124, which is aimed at the end of June, and has been in Firefox 3.0 since the betas.
