[Bug 330139] [NEW] Firefox Adobe Reader plugin hangs on accessing certain pages

[Michał Gołębiowski]

Public bug reported:

I encountered a standard-compliant site with PDF file embedded which
hangs my Adobe Reader plugin in Firefox - that is, browser is usable,
but CPU load is 100% and I'm unable to open another PDF file in Firefox
until I close the tab where I opened this site...

I copied the source and deleted as much pure HTML code as I could to make it more clear (it is still standard-compliant and it still doesn't work), here it is:
http://students.mimuw.edu.pl/~mg/launchpad/test.html

I tried a fresh Firefox profile and it still doesn't work; I also tried
opening it in Opera -- there were no problems with that.


Steps to reproduce:
0) Install Adobe Reader Firefox plugin from Medibuntu, if it's not installed
1) Open Firefox
2) Enter the site http://students.mimuw.edu.pl/~mg/launchpad/test.html
3) Try to open in Firefox another PDF in another tab -- it will not open
4) Close the tab displaying test.html site -- the second tab should now open PDF properly

What should happen:
in point (3) Firefox shouldn't hang, but it should properly open the site with embedded PDF file.
