592970 - XML/XSL rendering after using Panorama fails

Status: RESOLVED DUPLICATE of bug 591425

(Firefox Graveyard :: Panorama, defect, P3)

Description

[Julien BETI]

User-Agent:       Mozilla/5.0 (X11; Linux i686; rv:2.0b4) Gecko/20100818 Firefox/4.0b4
Build Identifier: Mozilla/5.0 (X11; Linux i686; rv:2.0b4) Gecko/20100818 Firefox/4.0b4

If you request a XML file that reference a XSL file for HTML generation, it works until you're using Panorama

Reproducible: Always

Steps to Reproduce:
1. Use Panorama to arrange your tabs
2. Open a XML file that reference an XSL file for HTML generation, like http://www.w3.org/Math/XSL/pmathml2.xml
Actual Results:  
The tab display freezes with the last displayed page

Expected Results:  
Display the rendered HTML page

I do reproduce this at work with an internal application that send heavy XML to the browser. But I find an URL on the internet, http://www.w3.org/Math/XSL/pmathml2.xml, that reproduces the issue.

If you restart Firefox and don't use Panorama to reorganize your tabs, the bug does not appear

http://www.w3schools.com/xsl/xsl_transformation.asp

is another example  (Minefield Windows7)
look for the "View results" link on the page,  whether the XML table is displayed depends on how the link is clicked - 

right click, select "Display in new Window"   works
right click, select "Display in new tab"   works
click on link gives new tab (the default Firefox setting in "Options" for how to open links is 'Open in new tab')  -does NOT work - gives a blank tab.

Is this related to bug 591425?

Attachment: Screen video capture FF4b6

I've now installed FF4b6, and the behavior is a bit different:
-1- As soon a s you haven't launched panorama, everything still works fine
-2- Once Panorama launched, I had the following behavior w/o identifying exactly which circumstances are involved:
-2.1- Page appear, and then disappear
-2.2- Page does not appear
-2.3- Page does not appear and after few seconds appears..

Hope it helps ;-)
