New version 9.0.1 on Windows 7 has a problem running JavaScript math iterations.

Dialog Error Box reads:
A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.
Script: http://www.classictesla.com/java/javatc/script/JTC_geotc.js:1299
The above dialog has never come up before. This program ran fine forever and has not changed. With Firefox 8, the program ran in 0.3 seconds. IMMEDIATELY as I allowed the browser to upgrade to 9.0.1, the program is now not working.
About 1000 people use this program. Knowing how slow fixes can be, I have to inform them not to allow FF to upgrade to version 9. Really sucks as I've been a FF fan forever.
If you go to that website, click the "Load Sample Coil" button, then scroll down and click the RUN JAVATC button, you'll see the problem
If there is a problem with the script, why only now after so many years of running? I can run it just fine on version 8. If there's something I can do on my end, I would love to (just tell me what the problem is).
My guess = "version 9 is limiting the number of iterations a script can run". This code use to run in 0.3 seconds and now is just hung. A very sad day for me. I guess I have to figure out how to go back to old version 8.

Only Firefox 9 seems to have that problem. Firefox 8 and Firefox 10 (beta) and later work. It helps a bit if I disable javascript.options.methodjit.content, but then it still takes 4 seconds compared to 0.2 or 0.3 seconds with the other Firefox versions. So that looks like a bug with the JIT compiler.

    So according to the wiki, the method for rolling back any package is to go to /var/cache/pacman/pkg/ and find whatever the old piece of software is. However, I've just recently installed Arch, and the only version of the kernel I have in there is 3.3
