For anyone interested - I’d you are using umatrix to block shit you can punch these lines into a new text file and import as blocklist, then commit it with the tiny arrow that points left toward the permanent list to save it permanently:

* www[.]googie-analytics[.]com * block

* kuurza[.]com * block

* cdn[.]polyfill[.]io * block

* polyfill[.]io * block

Remove the square brackets before saving the file - these are here to prevent hyperlinks and misclicks.

Edit: this is not a bulleted list, every line must start with an asterisk, just in case your instance doesn’t update edits made to comments quickly.
