Once on the ref URL, the page is blank.
You need to reload the URL in order to see the silverlight demo.

No problem in FF 4.0 b2

Reproducible: Always
I revert to changeset c7a4f2c4ba7a, then the problem is gone.
So, I guess landing of patch of Bug 502937 causes the problem,

I found this to be very tricky to reproduce. In current nightlies it isn't too hard to reproduce, but as you go back into May it starts taking quite a while to reproduce. I found that clearing the cache seems to be a key part in reproducing.

Given that, I was able to reproduce in a 2010-04-16 nightly, which is before changeset c7a4f2c4ba7a and bug 502937 landed.

Alice, do you find it easy to reproduce, even in older builds? Do you have any tips on reproducing? Could you maybe double check your regression range?
I am creating a New Profile each time for each build run.

Umm, I can not reproduce in 2010-04-16 nightly.
I think this has more to do with whether some important data is in the HTTP cache than anything else. Not a blocker unless it shows up much more frequently.

I need to try Alice's suggestion of using a new profile each time. I also want to try disabling lazyfc in current trunk to see if there are any confounding factors.
First Fail:

Blocks: 590422
Depends on: 562698
This problem is still there.
Yep, i can reproduce the issue with new profile.
And Comment 6 is wrong.

it seems to depend on networks activities and CPU usage.
No longer depends on: 562698
No longer blocks: 590422, lazyfc

Is this still an Issue for anyone who could repro?

The URL in the summary is WFM.
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0.1) Gecko/20100101 Firefox/4.0.1
Silverlight Plug-In - File: npctrl.dll - Version: 4.0.60310.0
With Fx 8 and Silverlight 4.0.60831.0, I can no longer reproduce with the ref. URL.
I close it as WFM.
