846408 - Some pages cause stall (15+ seconds input latency)

Status: RESOLVED WORKSFORME

(Firefox :: Untriaged, defect)

Description

[Russell Haley]

User Agent: Mozilla/5.0 (X11; Linux i686 on x86_64; rv:21.0) Gecko/20130228 Firefox/21.0
Build ID: 20130228042012

Steps to reproduce:

Navigate to, among other pages, http://www.rockpapershotgun.com/

The problem is present on any recent version of Nightly or Aurora, running 32 bit on AMD64 Debian sid, with this set of extensions:

Application: Firefox 21.0a2 (20130228042012)
Operating System: Linux (x86-gcc3)

- Adblock Plus 2.2.3
- Extension List Dumper 1.15.2
- Feedback 1.2.2
- Gecko Profiler 1.11.11 (Disabled)
- InlineDisposition 1.0.2.4
- MathML-fonts 1.1
- PDF Viewer 0.7.280
- Scriptish 0.1.8
- Tab Counter 1.9.6
- Tree Style Tab 0.14.2012122901



Actual results:

The input latency increased to over 15 seconds.  The latency went back to normal after closing the tab (which is somewhat difficult with 15 second input latency).

CPU usage is no higher than normal.


Expected results:

Input latency should have remained normal.

The console shows this

LoadPlugin: failed to initialize shared library /usr/lib/flashplugin-nonfree/libflashplayer.so [/usr/lib/flashplugin-nonfree/libflashplayer.so: wrong ELF class: ELFCLASS64]

Right as the problem hits, then once more every time the imput gets through.  I ran into issues with flash with 32 bit on AMD64 a while back, but I got the 32 bit plugin either from Adobe or from an x86 machine a while back, and put it in ~/.mozilla/plugins. 

Apparently an incompatibility arose with that version of Flash (or something -- it doesn't seem to print anything about what the problem is before falling back to the system library).  Downloading the current 32 bit .tar.gz from Adobe and putting that one in ~/.mozilla/plugins seems to have fixed the problem on that address, and likely any others.
