Site in question: http://www.topix.com/forum/city/coffeyv ... C2BLM65SUR
My specific issue is with the "Add to my Tracker" feature right there under the topic title. I click it, absolutely nothing happens. I expect that kind of thing internet-wide though, as I've got NoScript blocking almost everything until I specifically allow it.
So I click my NoScript icon, there are thirteen sites listed (aside from topix itself, auto-allowed). I've run into this on other sites too, some with twice that many. When there are just a few, it's no big deal to guess at which one the feature might need, and temp-allow sites one at a time, until I get the right one, then revoke all temp permissions and go back and allow just that one.
My question is, when there are a TON of sites listed, is there an easier way to figure out which ONE of those I'm going to need to allow to make a specific page feature work? My process stinks when the list is that long!
(Ok, so I actually just got done solving this, and I'm gonna tell you how, because I believe it could be a common issue, and the solution was a bit beyond average user knowledge.)
Out of those thirteen sites, I only needed TWO (including topix) for the site (including other features) to function properly. Here's how I found the second one:
Right-clicked on "Add to my Tracker" to see what my options were
Selected "Inspect Element", that looked like it might get me somewhere...
That brought up this, so I clicked the little arrow:

Copied both inner and outer HTML into Wordpad
Looked for URLs, spotted cachefly.net
Went back to the NoScript list, allowed that one, and VOILA! I can add that topic to my tracker now!
(After copying the HTML, the "X" (on mine) to take the page back to normal was teeny tiny in the bottom right corner.)
Logic dictates that by right-clicking on any site's page element that isn't working, selecting Inspect Element on it, and following the steps I took, one could use this solution anywhere this issue comes up. Quite acceptable to me, as opposed to process-of-elimination for an hour...
Ah, the joys of being an 8-year self-taught internet geek. You learn a lot when most of your troubleshooting consists of "wonder what happens if I click this?" Somehow, for the most part, (often as soon as I start asking for help), answers just happen. I really hope this helps others as well.
