Hello
Since several year I am dealing with browser problems. There are insulting adds appearing on the screen, there are strange network problems (I have to confirm several times that I am being human and not a bot (picture 1)), When I open certain websites there is nothing at all displayed (picture 2). Or even some variables are changed (through DOM ?). Here is an example, I was looking for a new flat at homegate.ch. I have set the rent limit to 1400 .-, and hit the search button. The result which was displayed is this (picture 3). I get flat results with a rent of 1790.- or even 1950.-. But actually I know those flats have a rent less than 1400.-. I found out, that there is a factor of lets say 1.45. If you divide the rent of the search results through 1.45, you get the real rent, this is true for all search results. My firefox settings are very security focused (HTTPS-only enabled, DNS over HTTPS, block cross site cookies,...), I am using a vpn client to connect to the internet. I guess the problem has something to do with code injection, XSS attack through JavaScript. But can t tell how, I guess cookies or session Token are involved in this attack. Can you please give me an advice, how to solve this annoying problem? Thanks in Advance
kind regards Stefan
