NoScript blocking XSS on Firefox Get Add-ons page

Post by Aimhere »

Hi,

This morning, I was using Firefox and went to the menu "Tools/Add-ons", but the "Get Add-ons" page did not load correctly (what did load made it sound like I was not connected to the Internet), and I saw a NoScript message about a XSS attempt being blocked. The only way I could get the "Get Add-ons" page to load was to click "Options/Unsafe reload".

Looking at the console, the relevant portion appears to be:

Code: Select all

(There may be non-relevant messages mixed in there, wasn't really sure what I was looking at.)

I know Firefox's developers recently changed the look and functionality of the Firefox "Get Add-ons" page (as loaded from the browser menus), but I could have sworn it loaded correctly prior to this.

How do I [re]configure the XSS options in NoScript to correct this, so I don't have to use "Unsafe reload" every time?

*Always* check the changelogs BEFORE updating that important software!
