From time to time, I review the list, and delete most commercial sites from it, as well as other sites that I don’t want to support.
To do that, I select “See all sites”, which appears as shown in the attached image. The trouble is that when I scroll through the list, and start deleting sites from the list, the sites shown in the list jump around every few seconds in the vicinity of the site/s most recently deleted. This means that it becomes impossible to delete the sites that I wish to delete.
As I click the mouse button to delete a site, the list suddenly changes and I delete a different site.
The site is only shows for a few milliseconds between the time that the list changes and the time I click the mouse button, which also means that I don’t know which site I deleted without wanting to delete it.
