XSS on blogspot/blogger

Post by eckstee »

Blogger has a new layout editor where you can see your changes live before you save them, and NoScript blocks an XSS request every time I go into it. With the request blocked, the editor doesn't work (my blog doesn't show in the lower pane), and upon doing an unsafe reload, everything works as expected.

I suspect this is because they use two domains, blogspot.com and blogger.com. I've already had third-party cookie issues because of this.

Adding the following line to the XSS exceptions list fixes the issue:

Code: Select all

Could you please show me the [NoScript XSS] line(s) you get in Tools|Error Console, so I can see if a more restrictive exception (or a different work-around) can be wired in next NoScript version?
Thanks.
