Firefox with Add-Images

[pfm]

While measuring was working properly yesterday from Dublin using Firefox, today there is on the same site a lot of images with URLs like this: "https://dtex4kvbppovt.cloudfront.net/images/1332a68badf11e3f7f69bf7364e79c0a7e2753bc.5316.png"

These seem to be add images from Firefox Ad Tab.

Could you please adjust the installation? Or did I made something wrong?

Thank you.

I have the same problem with those cloudfront images with tests from Manchester, Los Angeles, and Dulles, so other instances besides Dublin are also affected, it seems.

Ugh, thanks. Looking at a bunch of the images it looks like Mozilla is doing a fundraising campaign of some kind and may be opening a background tab or something. I'll see what I can do to get rid of it.
