Troubleshooting Tricks? (Walmart Reviews)

Is the FAQ the main documentation for NoScript? I don't see a manual/user guide.

Is there any documentation regarding advanced troubleshooting tricks?

I'm troubleshooting Walmart reviews, which don't show up, due to NoScript, and wondering what the best way to proceed is.

e.g., here, I see
Customer Product Reviews
1-4 of 37 total reviews
2345 ... 10 Next
but no reviews. I've allowed walmart.com, walmartimages.com, and bazaarvoice.com and there are still 5 domains blocked: bluekai, walmartwom, channelintelligence, richrelevance, and facebook. In general, what are good ways to figure out what I need to unblock to see the reviews without relying just on trial and error?
I tried selecting the reviews section of the page and going to view selection source, which prompted me to unblock bazaarvoice.com.

So, while I'm interested in knowing which domains I need to unblock, I'm more interested in learning how to figure out such problems myself, while aiming for safety and efficiency.

The reviews are backed by bazaarvoice.com. If you are blocking iframes on trusted you also need to allow its iframe (blocked objects menu) and reload the page.

Beside trial and error and examining the blocked hosts (whois to get company name, visit them, search for them, all to get a sense of what functionality they provide) The most direct (albeit advanced) way to troubleshoot is with the error console. It will show what NS is blocking (beyond the scripts in the menu), and more significantly for this case, content JS errors resulting from blocked scripts.

One of them:

Code: Select all

Error: $BV is not defined
Source File: http://www.walmart.com/ip/AT-T-GoPhone-Prepaid-Samsung-A107-Cell-Phone-Silver/15421486#Product+Reviews
Line: 3438
will take you to the error line in page source, the context around which will show (you have to know at least some JS and html) that it has to do with a blocked script from bazaarvoice and that it's related to reviews

Thanks. My initial troubleshooting using 'View Selection Source' was on the mark - sort of. :mrgreen: I'd already unblocked bazaarvoice.com, but the reviews load into the page so slowly I didn't notice they'd finally loaded.
