Constant XSS Warnings

Frequently on websites, I am constantly prompted by NoScript's XSS Warning pop window. It's frequently alerting me that a document request from <numerical subdomain>.fls.doubleclick.net is trying to redirect to adservice.google.com. The doubleclick sites always start with a numerical subdomain.

I have tried finding a way to just block anything from doubleclick to google and stop alerting me about it, but I cannot find a feature like this. I've also tried following the FAQ (https://noscript.net/faq#qa4_3) to just turn off XSS notifications completely, but what the FAQ states doesn't exist. It says go to NoScript Options, then Notifications, then XSS preferences. There is no Notifications section, and certainly no XSS preferences.

I feel like I have clicked over a thousand times with these XSS warnings. Is there a way I can globally block doubleclick and/or stop being alerted to this?

What script permission do you have set for doubleclick.net?

If look in the Per-Site Permissions, I do not see doubleclick.net listed. Should I manually add it, then set it to block here?

You could try manually adding it and setting it to Untrusted. But first, how do you have the Default preset configured?

Sorry for the late response getting back to you. This is my work PC, and I was out over the weekend.

I manually added doubleclick.net and set it to Untrusted; I'll see how that goes.

When you ask about the "default preset", do you mean on the first General tab options? I haven't made any changes here, so it's the default that it installs at, which is allow the following:
script, object, media, frame, font, webgl, other. That seems like a lot for Default, but that's how it is. Do you think I should change this?

Thanks for your help! I really appreciate it!

Yes that one.

There's your problem. That is certainly *not* the default for Default!

Thank you for the quick reply.

I'll make the changes to the Default as it stated in the other thread you mentioned.

I don't know how any of this might have changed. I'm just now finding these options for the first time, and I did make any changes knowingly.

Hopefully this works, and thanks again for your help and guidance!
