Hello,
I would like to ask if NoScript extension in Mozilla browser could change default network.trr.excluded-domains: 'undefined'
to
network.trr.excluded-domains: 'sbl-xbl.spamhaus.org, localhost.that.never.exists'
I tested now, I installed NoScript, then visited some websites, then uninstalled extension but no change - network.trr.excluded-domains is 'undefined'

I contacted Mozilla support and they advised me to search only for third-party software/apps because they set up it as 'undefined'. Then I checked and also contacted antivir support but no relations to change this setting.
The last to check remained NoScript.

Please give me a feedback if NoScript (maybe some previous versions) could cause this change in set-up of network.trr.excluded-domains.

NoScript has no access to that setting at all. There is no WebExtensions API to either read or alter that value.
