The report that shows when I do that is from January 28. I'm not sure why. I repeatedly crashed firefox this morning by going to the web site in hopes of generating a newer report, but nothing shows up.

The Jan. 28 report is

I will try once more to generate a newer report and will post it if I can generate it

OK, this may help. The amplebeauties site links to an audio player at

It's that audioplayer that is crashing firefox. 

The same crash happens by going to and hitting "play" on the default player and there, you don't need a login to see the problem.
I just tried the site on one Windows 7 machine and was not able to crash. Do you have any addons installed in your profile? I have another Windows 7 machine in the QA lab that I can try.

I have nothing special in my profile. 

The add ons are various versions of the Java console and Microsoft net framework 1.1

(I also have mcafee running)

On plugins, I have acrobat

aol media playback plug in

download updater

download updater2

Google earth

And plug ins for quicktime, real player and real jukebox, rim handheld application loader, and various microsoft add ons (for siverlight for example)

There is a plug in for Metastream3 but it is disabled. 

I do have the 9.1 beta version of adobe flash if it matters.

Opening does not crash the browser. Hitting play crashes it. 

(the other website i cited, starts playing automatically when certain profiles are open, which crashes my browser.)
Since that player appears to be flash-based I would say it may be due to the fact you are using an older version of flash. I would try updating to the latest version at to see if the issue persists. I am using the latest version of flash form the site when testing.

I typed the wrong version of the flash plug in. I have 10.1 beta 2 (not 9.1 as i typed). Adobe updated to beta 3 today, so if it's flash related, I'll try the update.

Marcia. You were EXACTLY right on it being due to flash. 

10.1 beta 3 fixed it. 

You can close this now. Thanks for the help.
