STR:
1) Visit cnn.com
2) Open the script debugger
3) Observe the huge labels in the script list

In SS__getScriptLabel we trim the query string before deciding on a unique, short label for the script. In this case, however, the query string is what differentiates the script URLs.

The best mitigation I came up with is using the path info as usual, but instead of appending the whole query string, just add a unique subset of it, probably with ellipsis characters before and after.

Duplicate of this bug: 759629
http://rawkes.com/ from bug 759629 is another good case for huge script labels due to long query strings. In this particular case however, the query string delimiter character '?' is missing, which confuses SS__trimUrlQuery. I'm not even sure such URLs are valid:

Sometimes I'm surprised the whole internet thing even works...

v1.1

I just realized that until now, the whole "for (let i = 0; i < vs._scripts.itemCount; i++)" check for script urls was incorrect, because there was no 1:1 relationship between the test urls array and the actual added urls in the dropdown. This means that, although it worked and the order wasn't important, not all the urls were tested. Fixed in this version.
