Clicking on Google shopping links still broken

[gridflash]

We reported this problem in January Now it’s gotten worse.
When clicking on any Google shopping link you get “This site can’t be reached” then in a few seconds you get to the site. Switching Shields makes no difference.
But now when we click on any Home Depot link in Google shopping we get a black screen,
No Message. theURL changes to ‘https://8808.xg4ken.com/trk/v1?prof=410’.
The point here is that the problem is getting worse and the browser is becoming unusable.
I assume if it was fixable tech support would have done so by now.
But I’m open to any suggestions.
