Reproducible: Always Steps to Reproduce: 1. go to http://www.amazon.com/gp/goldbox/ref=sv_gb_0# Actual Results: 2. that's all, full site doesn't display 3. try to open Firefox 3.6 to see if problem on site or 4.0, 3.6 won't start, ONLY OTHER INSTANCES OF 4.0 4. remove 4.0 from computer
You can't run 3.6 and 4.0 at the same time but you don't have to uninstall 4.0 to run 3.6. Just close all Firefox windows and you can select the version you want to run. 2 independent applications should not write to the same files in your userprofile or they would get damaged. The userprofile contains your bookmark, cookie etc files but that is outside of the scope of this bug report and is a question for the support. now the bug: I can see the problem with Seamonkey trunk and FF4.0b9 on win32. There are many errors in the error console and the safemode or disabling the html5 parser doesn't help. I will try to find a regression range.

Boris: Do you have an idea what this could be ? There is a TM merge in that regression window but the safemode doesn't help..
The TM merge is the most likely issue. Matti, can you figure out the regression range on that branch using TM nightlies? The intersection of the two ranges might be enlightening.

My best guess is that jimb broke something with his strict mode work.
Note that the page's script are in strict mode, btw. So it's possible that they're just doing stuff that's not allowed there.
Though I only see one JS error loading the page: Error: assignment to undeclared variable ourPercentOff Source File: http://z-ecx.images-amazon.com/images/G/01/goldbox/client-side/gbld_js-v39._V174650570_.js Line: 5610 That's in the "multi_price_block" function. The "price_block" function, which is similar, declares that var. Of course maybe there's something else going on and they're catching the exception or something....
Well.... yes, but why did this only start being a problem in the regression range from comment 5?
Why wouldn't it? Using an old build loads the new site code. Before the first bits of strict mode landed nothing would have gone wrong. After they landed (which occurred in that regression range), the first strict mode violation would be an error. The first violation in this script is the one hit here.
Oh, I missed that the undeclared variable thing was in the range. I thought it had landed earlier.... OK, then!
Kev, any update? /be
It's been fixed, I thought... or was that another, related error? Current and upcoming offers are displayed for me right now...
Yeah, this looks fixed. No more exceptions.
